1 John 3:11-16

Verse 11

For this is the message - See 1Jn 1:5. From the beginning God hath taught men that they should love one another. How essentially necessary this is to the comfort and well-being of man in this state of trial and difficulty, every sensible man must see. All are dependent upon all; all upon each, and each upon all. Mutual love makes this dependence pleasant and doubly profitable. Nothing can be more pleasing to an ingenuous and generous mind than to communicate acts of kindness.
Verse 12

Not as Cain - Men should not act to each other as Cain did to his brother Abel. He murdered him because he was better than himself. But who was Cain? Εκ του πονηρου ην, he was of the devil. And who are they who, through pride, lust of power, ambition, gain, etc., murder each other in wars and political contentions? Εκ του πονηρου εισι. To attempt to justify the principle, and excuse the instigators, authors, abettors, etc., of such wars, is as vain as it is wicked. They are opposed to the nature of God, and to that message which he has sent to man from the beginning: Love one another. Love your enemies. Surely this does not mean, Blow out their brains, or, Cut their throats. O, how much of the spirit, temper, and letter of the Gospel have the nations of the world, and particularly the nations of Europe, to learn!

And wherefore slew he him? - What could induce a brother to imbrue his hands in a brother's blood? Why, his brother was righteous, and he was wicked; and the seed of the wicked one which was in him induced him to destroy his brother, because the seed of God - the Divine nature, was found in him.
Verse 13

Marvel not - if the world hate you - Expect no better treatment from unconverted Jews and Gentiles than Abel received from his wicked and cruel brother. This was a lesson to the Church, preparatory to martyrdom. Expect neither justice nor mercy from the men who are enemies of God. They are either full of malice and envy, hateful, hating one another, or they are specious, hollow, false, and deceitful. "A foe to God was ne'er true friend to Man."
Verse 14

We know that we have passed from death unto life - Death and life are represented here as two distinct territories, states, or kingdoms, to either of which the inhabitants of either may be removed. This is implied in the term μεταβεβηκαμεν, from μετα, denoting change of place, and βαινω, I go. It is the same figure which St. Paul uses, Col 1:13 : Who hath delivered us from the power of darkness, and translated us into the kingdom of the Son of his love. The believers to whom St. John writes had been once in the region and shadow of death, in the place where sin and death reigned, whose subjects they were; but they had left that kingdom of oppression, wretchedness, and wo, and had come over to the kingdom of life, whose king was the Prince and Author of life; where all was liberty, prosperity, and happiness; where life and love were universally prevalent, and death and hatred could not enter. We know, therefore, says the apostle, that we are passed over from the territory of death to the kingdom of life, because we love the brethren, which those who continue in the old kingdom - under the old covenant, can never do; for he that loveth not his brother abideth in death. He has never changed his original residence. He is still an unconverted, unrenewed sinner.
Verse 15

Whosoever hateth his brother is a murderer - He has the same principle in him which was in Cain, and it may lead to the same consequences.

No murderer hath eternal life - Eternal life springs from an indwelling God; and God cannot dwell in the heart where hatred and malice dwell. This text has been quoted to prove that no murderer can be saved. This is not said in the text; and there have been many instances of persons who have been guilty of murder having had deep and genuine repentance, and who doubtless found mercy from his hands who prayed for his murderers, Father, forgive them; for they know not what they do! It is, however, an awful text for the consideration of those who shed human blood on frivolous pretences, or in those wars which have their origin in the worst passions of the human heart.
Verse 16

Hereby perceive we the love of God - This sixteenth verse of this third chapter of John's first epistle is, in the main, an exact counterpart of the sixteenth verse of the third chapter of St. John's gospel: God so loved the world, that he gave his only-begotten Son, etc. Here the apostle says, We perceive, εγνωκαμεν, we have known, the love of God, because he laid down his life for us. Of God is not in the text, but it is preserved in one MS., and in two or three of the versions; but though this does not establish its authenticity, yet του Θεου, of God, is necessarily understood, or του Χριστου, of Christ, as Erpen's Arabic has it; or αυτου εις ἡμας, his love to us, as is found in the Syriac. A higher proof than this of his love Christ could not have possibly given to the children of men.

We ought to lay down our lives for the brethren - We should risk our life to save the lives of others; and we should be ready to lay down our lives to redeem their souls when this may appear to be a means of leading them to God.
