1 John 3:2-4

Amplified Bible

² Beloved, we are [even here and] now children of God, and it is not yet made clear what we will be [after His coming]. We know that when He comes and is revealed, we will [as His children] be like Him, because we will see Him just as He is [in all His glory]. ³ And everyone who has this hope [confidently placed] in Him purifies himself, just as He is pure (holy, undefiled, guiltless).

⁴ Everyone 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].
