2:7 {6} Brethren, I write no new commandment unto you, but an old commandment which ye had from the beginning. The old commandment is the word which ye have heard from the beginning.
(6) The apostle expounding the commandment of charity towards one another, tells first that when he urges holiness, he brings no new idea of life (as they use to do who devise traditions one after another) but reminds them of that same law which God gave in the beginning, that is, by Moses, at the time that God began to make laws for his people.
2:7 I write no new commandment unto you. He writes in substance what was commanded from the beginning when he bids them walk as Christ walks.
The old commandment is the word which ye have heard. The Gospel. Its substance is condensed by Christ into the words: Follow me.
From the beginning. Their first hearing of the gospel.
2:7 When I speak of keeping his word, I write not a new commandment - I do not speak of any new one. But the old commandment, which ye had - Even from your forefathers.
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.
