Here is a way to examine the real disposition of your own heart toward such. Would you cheerfully do them kindness and help them to the extent of your ability to see the error of their way and to overcome it? Can you tenderly pray for them and patiently bear with their weakness, their ignorance and lack of development, and try by a noble example to show them a more excellent way? If such be the case, then it is the sin that you despise, and not the sinner. The sin you should hate, but the sinner, never. Not until God's unerring judgment declares that the sin and the sinner are inseparably linked together may love let go its hold upon a brother man.
The perfection of love is love for enemies; nor is there anything in love harder to develop than love for enemies. He who can love, bless, do good to and pray for his enemies, is indeed rich in character; and if he maintains this quality firm unto the end, he will be sure of an entrance into the everlasting Kingdom; for this presupposes proper love for God, Jesus, the brethren and the world of mankind, all of which combined constitute perfect love.
