1 John 3:3-6

3And everyone who has this hope [confidently placed] in Him purifies himself, just as He is pure (holy, undefiled, guiltless).

4Everyone who practices sin also practices lawlessness; and sin is lawlessness [ignoring God’s law by action or neglect or by tolerating wrongdoing—being unrestrained by His commands and His will].

5You know that He appeared [in visible form as a man] in order to take away sins; and in Him there is [absolutely] no sin [for He has neither the sin nature nor has He committed sin or acts worthy of blame].

6No one who abides in Him [who remains united in fellowship with Him—deliberately, knowingly, and habitually] practices sin. No one who habitually sins has seen Him or known Him.
