By this perceive we the love of God, because he laid down his life for us: and we ought to lay down our lives for the brethren.
All Commentaries on 1 John 3:16 Go To 1 John 3
Tertullian of Carthage
AD 220
John, in fact, exhorts us to lay down our lives even for our brethren. Too, that we may be able to quench the darts of the devil, when doubtless we resist him, and sustain his assaults in their utmost force. Accordingly John also teaches that we must lay down our lives for the brethren.
