1 John 3:23

23 and this is His command, that we may believe in the name of His Son Jesus Christ, and may love one another, even as He did give command to us,

1 John 3:23 In-Context

21 Beloved, if our heart may not condemn us, we have boldness toward God,
22 and whatever we may ask, we receive from Him, because His commands we keep, and the things pleasing before Him we do,
23 and this is His command, that we may believe in the name of His Son Jesus Christ, and may love one another, even as He did give command to us,
24 and he who is keeping His commands, in Him he doth remain, and He in him; and in this we know that He doth remain in us, from the Spirit that He gave us.
