1 John 3:20

16 By this we know what love is: Jesus laid down His life for us, and we ought to lay down our lives for our brothers.

17 If anyone with earthly possessions sees his brother in need, but withholds his compassion from him, how can the love of God abide in him?

18 Little children, let us love not in word and speech, but in action and truth.

19 And by this we will know that we belong to the truth, and will assure our hearts in His presence:

20 Even if our hearts condemn us, God is greater than our hearts, and He knows all things.

21 Beloved, if our hearts do not condemn us, we have confidence before God,

22 and we will receive from Him whatever we ask, because we keep His commandments and do what is pleasing in His sight.

23 And this is His commandment: that we should believe in the name of His Son, Jesus Christ, and we should love one another just as He commanded us.

24 Whoever keeps His commandments remains in God, and God in him. And by this we know that He remains in us: by the Spirit He has given us.
