[Heb 4:14 KJV] 14 Seeing then that we have a great high priest, that is passed into the heavens, Jesus the Son of God, let us hold fast [our] profession.

[1Co 1:17-18, 21, 31 KJV] 17 For Christ sent me not to baptize, but to preach the gospel: not with wisdom of words, lest the cross of Christ should be made of none effect. 18 For the preaching of the cross is to them that perish foolishness; but unto us which are saved it is the power of God. ... 21 For after that in the wisdom of God the world by wisdom knew not God, it pleased God by the foolishness of preaching to save them that believe. ... 31 That, according as it is written, He that glorieth, let him glory in the Lord.

[1Co 1:27-29 KJV] 27 But God hath chosen the foolish things of the world to confound the wise; and God hath chosen the weak things of the world to confound the things which are mighty; 28 And base things of the world, and things which are despised, hath God chosen, [yea], and things which are not, to bring to nought things that are: 29 That no flesh should glory in his presence.

[1Co 2:1-8, 12-13 KJV] 1 And I, brethren, when I came to you, came not with excellency of speech or of wisdom, declaring unto you the testimony of God. 2 For I determined not to know any thing among you, save Jesus Christ, and him crucified. 3 And I was with you in weakness, and in fear, and in much trembling. 4 And my speech and my preaching [was] not with enticing words of man's wisdom, but in demonstration of the Spirit and of power: 5 That your faith should not stand in the wisdom of men, but in the power of God. 6 Howbeit we speak wisdom among them that are perfect: yet not the wisdom of this world, nor of the princes of this world, that come to nought: 7 But we speak the wisdom of God in a mystery, [even] the hidden [wisdom], which God ordained before the world unto our glory: 8 Which none of the princes of this world knew: for had they known [it], they would not have crucified the Lord of glory. ... 12 Now we have received, not the spirit of the world, but the spirit which is of God; that we might know the things that are freely given to us of God. 13 Which things also we speak, not in the words which man's wisdom teacheth, but which the Holy Ghost teacheth; comparing spiritual things with spiritual.

[1Co 14:1-25 KJV] 1 Follow after charity, and desire spiritual [gifts], but rather that ye may prophesy. 2 For he that speaketh in an [unknown] tongue speaketh not unto men, but unto God: for no man understandeth [him]; howbeit in the spirit he speaketh mysteries. 3 But he that prophesieth speaketh unto men [to] edification, and exhortation, and comfort. 4 He that speaketh in an [unknown] tongue edifieth himself; but he that prophesieth edifieth the church. 5 I would that ye all spake with tongues, but rather that ye prophesied: for greater [is] he that prophesieth than he that speaketh with tongues, except he interpret, that the church may receive edifying. 6 Now, brethren, if I come unto you speaking with tongues, what shall I profit you, except I shall speak to you either by revelation, or by knowledge, or by prophesying, or by doctrine? 7 And even things without life giving sound, whether pipe or harp, except they give a distinction in the sounds, how shall it be known what is piped or harped? 8 For if the trumpet give an uncertain sound, who shall prepare himself to the battle? 9 So likewise ye, except ye utter by the tongue words easy to be understood, how shall it be known what is spoken? for ye shall speak into the air. 10 There are, it may be, so many kinds of voices in the world, and none of them [is] without signification. 11 Therefore if I know not the meaning of the voice, I shall be unto him that speaketh a barbarian, and he that speaketh [shall be] a barbarian unto me. 12 Even so ye, forasmuch as ye are zealous of spiritual [gifts], seek that ye may excel to the edifying of the church. 13 Wherefore let him that speaketh in an [unknown] tongue pray that he may interpret. 14 For if I pray in an [unknown] tongue, my spirit prayeth, but my understanding is unfruitful. 15 What is it then? I will pray with the spirit, and I will pray with the understanding also: I will sing with the spirit, and I will sing with the understanding also. 16 Else when thou shalt bless with the spirit, how shall he that occupieth the room of the unlearned say Amen at thy giving of thanks, seeing he understandeth not what thou sayest? 17 For thou verily givest thanks well, but the other is not edified. 18 I thank my God, I speak with tongues more than ye all: 19 Yet in the church I had rather speak five words with my understanding, that [by my voice] I might teach others also, than ten thousand words in an [unknown] tongue. 20 Brethren, be not children in understanding: howbeit in malice be ye children, but in understanding be men. 21 In the law it is written, With [men of] other tongues and other lips will I speak unto this people; and yet for all that will they not hear me, saith the Lord. 22 Wherefore tongues are for a sign, not to them that believe, but to them that believe not: but prophesying [serveth] not for them that believe not, but for them which believe. 23 If therefore the whole church be come together into one place, and all speak with tongues, and there come in [those that are] unlearned, or unbelievers, will they not say that ye are mad? 24 But if all prophesy, and there come in one that believeth not, or [one] unlearned, he is convinced of all, he is judged of all: 25 And thus are the secrets of his heart made manifest; and so falling down on [his] face he will worship God, and report that God is in you of a truth.

[2Co 2:14-16 KJV] 14 Now thanks [be] unto God, which always causeth us to triumph in Christ, and maketh manifest the savour of his knowledge by us in every place. 15 For we are unto God a sweet savour of Christ, in them that are saved, and in them that perish: 16 To the one [we are] the savour of death unto death; and to the other the savour of life unto life. And who [is] sufficient for these things?

[2Co 3:12-13 KJV] 12 Seeing then that we have such hope, we use great plainness of speech: 13 And not as Moses, [which] put a vail over his face, that the children of Israel could not stedfastly look to the end of that which is abolished:

[Col 1:23-29 KJV] 23 If ye continue in the faith grounded and settled, and [be] not moved away from the hope of the gospel, which ye have heard, [and] which was preached to every creature which is under heaven; whereof I Paul am made a minister; 24 Who now rejoice in my sufferings for you, and fill up that which is behind of the afflictions of Christ in my flesh for his body's sake, which is the church: 25 Whereof I am made a minister, according to the dispensation of God which is given to me for you, to fulfil the word of God; 26 [Even] the mystery which hath been hid from ages and from generations, but now is made manifest to his saints: 27 To whom God would make known what [is] the riches of the glory of this mystery among the Gentiles; which is Christ in you, the hope of glory: 28 Whom we preach, warning every man, and teaching every man in all wisdom; that we may present every man perfect in Christ Jesus: 29 Whereunto I also labour, striving according to his working, which worketh in me mightily.

[1Th 2:3-12 KJV] 3 For our exhortation [was] not of deceit, nor of uncleanness, nor in guile: 4 But as we were allowed of God to be put in trust with the gospel, even so we speak; not as pleasing men, but God, which trieth our hearts. 5 For neither at any time used we flattering words, as ye know, nor a cloke of covetousness; God [is] witness: 6 Nor of men sought we glory, neither of you, nor [yet] of others, when we might have been burdensome, as the apostles of Christ. 7 But we were gentle among you, even as a nurse cherisheth her children: 8 So being affectionately desirous of you, we were willing to have imparted unto you, not the gospel of God only, but also our own souls, because ye were dear unto us. 9 For ye remember, brethren, our labour and travail: for labouring night and day, because we would not be chargeable unto any of you, we preached unto you the gospel of God. 10 Ye [are] witnesses, and God [also], how holily and justly and unblameably we behaved ourselves among you that believe: 11 As ye know how we exhorted and comforted and charged every one of you, as a father [doth] his children, 12 That ye would walk worthy of God, who hath called you unto his kingdom and glory.

[2Ti 2:15 KJV] 15 Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth.

[Tit 3:8-9 KJV] 8 [This is] a faithful saying, and these things I will that thou affirm constantly, that they which have believed in God might be careful to maintain good works. These things are good and profitable unto men. 9 But avoid foolish questions, and genealogies, and contentions, and strivings about the law; for they are unprofitable and vain.

[Psa 57:7 KJV] 7 My heart is fixed, O God, my heart is fixed: I will sing and give praise.

[Mat 10:22 KJV] 22 And ye shall be hated of all [men] for my name's sake: but he that endureth to the end shall be saved.

[1Co 15:58 KJV] 58 Therefore, my beloved brethren, be ye stedfast, unmoveable, always abounding in the work of the Lord, forasmuch as ye know that your labour is not in vain in the Lord.

[Heb 13:9 KJV] 9 Be not carried about with divers and strange doctrines. For [it is] a good thing that the heart be established with grace; not with meats, which have not profited them that have been occupied therein.

[Deu 7:8-9 KJV] 8 But because the LORD loved you, and because he would keep the oath which he had sworn unto your fathers, hath the LORD brought you out with a mighty hand, and redeemed you out of the house of bondmen, from the hand of Pharaoh king of Egypt. 9 Know therefore that the LORD thy God, he [is] God, the faithful God, which keepeth covenant and mercy with them that love him and keep his commandments to a thousand generations;

[Jos 23:14 KJV] 14 And, behold, this day I [am] going the way of all the earth: and ye know in all your hearts and in all your souls, that not one thing hath failed of all the good things which the LORD your God spake concerning you; all are come to pass unto you, [and] not one thing hath failed thereof.

[2Sa 7:28 KJV] 28 And now, O Lord GOD, thou [art] that God, and thy words be true, and thou hast promised this goodness unto thy servant:

[1Ki 8:23-24, 56 KJV] 23 And he said, LORD God of Israel, [there is] no God like thee, in heaven above, or on earth beneath, who keepest covenant and mercy with thy servants that walk before thee with all their heart: 24 Who hast kept with thy servant David my father that thou promisedst him: thou spakest also with thy mouth, and hast fulfilled [it] with thine hand, as [it is] this day. ... 56 Blessed [be] the LORD, that hath given rest unto his people Israel, according to all that he promised: there hath not failed one word of all his good promise, which he promised by the hand of Moses his servant.

[Psa 89:1-2, 5, 8, 14, 24, 28, 33-34 KJV] 1 [[Maschil of Ethan the Ezrahite.]] I will sing of the mercies of the LORD for ever: with my mouth will I make known thy faithfulness to all generations. 2 For I have said, Mercy shall be built up for ever: thy faithfulness shalt thou establish in the very heavens. ... 5 And the heavens shall praise thy wonders, O LORD: thy faithfulness also in the congregation of the saints. ... 8 O LORD God of hosts, who [is] a strong LORD like unto thee? or to thy faithfulness round about thee? ... 14 Justice and judgment [are] the habitation of thy throne: mercy and truth shall go before thy face. ... 24 But my faithfulness and my mercy [shall be] with him: and in my name shall his horn be exalted. ... 28 My mercy will I keep for him for evermore, and my covenant shall stand fast with him. ... 33 Nevertheless my lovingkindness will I not utterly take from him, nor suffer my faithfulness to fail. 34 My covenant will I not break, nor alter the thing that is gone out of my lips.

[Isa 54:9-10 KJV] 9 For this [is as] the waters of Noah unto me: for [as] I have sworn that the waters of Noah should no more go over the earth; so have I sworn that I would not be wroth with thee, nor rebuke thee. 10 For the mountains shall depart, and the hills be removed; but my kindness shall not depart from thee, neither shall the covenant of my peace be removed, saith the LORD that hath mercy on thee.
