1 John 3:2-3

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