1 John 4:17-19

17 Our love will be manifested in all its perfection by our having complete confidence on the day of the Judgement; because just what He is, we also are in the world.

18 Love has in it no element of fear; but perfect love drives away fear, because fear involves pain, and if a man gives way to fear, there is something imperfect in his love.

19 We love because God first loved us.
