2:8 {7} Again, a new commandment I write unto you, {h} which thing is true in him and in you: because the darkness is past, and the true light now shineth.
(7) He adds that the doctrine indeed is old, but it is in a way new, both in respect to Christ, and also to us: in whom he through the gospel, engraves his law effectually, not in tables of stone, but in our minds. {h} Which thing (that is, that the doctrine is new which I write to you) is true in him, and in you.
2:8 Again, a new commandment I write unto you. Yet this commandment, the substance of which is brotherly love, is in one sense new, because it was first taught them by Christ. See Joh 13:34.
Which thing is true in him and in you. Its truth is shown in the life of Christ and in your life.
Because the darkness is past, and the true light now shineth. The truth of the new commandment is shown because you have come out of the darkness and are walking in the light that shineth. He that keeps the new commandment walks in the light.
2:8 Again, I do write a new commandment to you - Namely, with regard to loving one another. A commandment which, though it also was given long ago, yet is truly new in him and in you. It was exemplified in him, and is now fulfilled by you, in such a manner as it never was before. For there is no comparison between the state of the Old Testament believers, and that which ye now enjoy: the darkness of that dispensation is passed away; and Christ the true light now shineth in your hearts.
2:3-11 What knowledge of Christ can that be, which sees not that he is most worthy of our entire obedience? And a disobedient life shows there is neither religion nor honesty in the professor. The love of God is perfected in him that keeps his commandments. God's grace in him attains its true mark, and produces its sovereign effect as far as may be in this world, and this is man's regeneration; though never absolutely perfect here. Yet this observing Christ's commands, has holiness and excellency which, if universal, would make the earth resemble heaven itself. The command to love one another had been in force from the beginning of the world; but it might be called a new command as given to Christians. It was new in them, as their situation was new in respect of its motives, rules, and obligations. And those who walk in hatred and enmity to believers, remain in a dark state. Christian love teaches us to value our brother's soul, and to dread every thing hurtful to his purity and peace. Where spiritual darkness dwells, in mind, the judgment, and the conscience will be darkened, and will mistake the way to heavenly life. These things demand serious self-examination; and earnest prayer, that God would show us what we are, and whither we are going.
