11 This is the message you have heard from the beginning: We should love one another. 12 We must not be like Cain, who belonged to the evil one and killed his brother. And why did he kill him? Because Cain had been doing what was evil, and his brother had been doing what was righteous. 13 So don't be surprised, dear brothers and sisters, if the world hates you.
14 If we love our brothers and sisters who are believers, it proves that we have passed from death to life. But a person who has no love is still dead. 15 Anyone who hates another brother or sister is really a murderer at heart. And you know that murderers don't have eternal life within them. 16 We know what real love is because Jesus gave up his life for us. So we also ought to give up our lives for our brothers and sisters. 17 If someone has enough money to live well and sees a brother or sister in need but shows no compassion-how can God's love be in that person?

Commentary on 1 John 3:11-15
(Read 1 John 3:11-15)
We should love the Lord Jesus, value his love, and therefore love all our brethren in Christ. This love is the special fruit of our faith, and a certain sign of our being born again. But none who rightly know the heart of man, can wonder at the contempt and enmity of ungodly people against the children of God. We know that we are passed from death to life: we may know it by the evidences of our faith in Christ, of which love to our brethren is one. It is not zeal for a party in the common religion, or affection for those who are of the same name and sentiments with ourselves. The life of grace in the heart of a regenerate person, is the beginning and first principle of a life of glory, whereof they must be destitute who hate their brother in their hearts.
Commentary on 1 John 3:16-21
(Read 1 John 3:16-21)
Here is the condescension, the miracle, the mystery of Divine love, that God would redeem the church with his own blood. Surely we should love those whom God has loved, and so loved. The Holy Spirit, grieved at selfishness, will leave the selfish heart without comfort, and full of darkness and terror. By what can it be known that a man has a true sense of the love of Christ for perishing sinners, or that the love of God has been planted in his heart by the Holy Spirit, if the love of the world and its good overcomes the feelings of compassion to a perishing brother? Every instance of this selfishness must weaken the evidences of a man's conversion; when habitual and allowed, it must decide against him. If conscience condemn us in known sin, or the neglect of known duty, God does so too. Let conscience therefore be well-informed, be heard, and diligently attended to.
