[1Co 9:23-27 KJV] 23 And this I do for the gospel's sake, that I might be partaker thereof with [you]. 24 Know ye not that they which run in a race run all, but one receiveth the prize? So run, that ye may obtain. 25 And every man that striveth for the mastery is temperate in all things. Now they [do it] to obtain a corruptible crown; but we an incorruptible. 26 I therefore so run, not as uncertainly; so fight I, not as one that beateth the air: 27 But I keep under my body, and bring [it] into subjection: lest that by any means, when I have preached to others, I myself should be a castaway.

[Gal 5:7 KJV] 7 Ye did run well; who did hinder you that ye should not obey the truth?

[2Pe 2:1 KJV] 1 But there were false prophets also among the people, even as there shall be false teachers among you, who privily shall bring in damnable heresies, even denying the Lord that bought them, and bring upon themselves swift destruction.
