If anyone sees his brother committing a sin not leading to death, he shall ask and God will for him give life to those who commit sin not leading to death. There is a sin leading to death; I do not say that he should make request for this. All unrighteousness is sin, and there is a sin not leading to death. We know that no one who is born of God sins; but He who was born of God keeps him, and the evil one does not touch him.
(1Jn 5:16-18)
And I, brethren, could not speak to you as to spiritual, but as to fleshy, as to minors in Christ." Milk I give you to drink, not solid food, for not as yet were you able. Nay, still, not even now are you able, for you are still fleshly. For where there is jealousy and strife among you, are you not fleshly and walking according to man? For whenever anyone may be saying, "I, indeed, am of Paul,yet another, "I, of Apollos,will he not be fleshly?
(1Co 3:1-4)
This is the message we have heard from Him and announce to you, that God is Light, and in Him there is no darkness at all. If we say that we have fellowship with Him and yet walk in the darkness, we lie and do not practice the truth; but if we walk in the Light as He Himself is in the Light, we have fellowship with one another, and the blood of Jesus His Son cleanses us from all sin. If we say that we have no sin, we are deceiving ourselves and the truth is not in us. If we confess our sins, He is faithful and righteous to forgive us our sins and to cleanse us from all unrighteousness. If we say that we have not sinned, we make Him a liar and His word is not in us.
(1Jn 1:5-10)
Now if any man builds on the foundation with gold, silver, precious stones, wood, hay, straw, each man's work will become evident; for the day will show it because it is to be revealed with fire, and the fire itself will test the quality of each man's work. If any man's work which he has built on it remains, he will receive a reward. If any man's work is burned up, he will suffer loss; but he himself will be saved, yet so as through fire.
(1Co 3:12-15)
