2:9 {8} He that saith he is in the light, and hateth his brother, is in darkness even until now.
(8) Now he comes to the second table, that is, to charity towards one another, and denies that a man has true light in him, or is indeed regenerate and the son of God, who hates his brother: and such a one wanders miserably in darkness, may he never brag of great knowledge of God for he knowingly and willingly casts himself headlong into hell.
2:9 He that saith he is the light, etc. If one hates his brother he demonstrates that he is in darkness.
2:9 He that saith he is in the light - In Christ, united to him. And hateth his brother - The very name shows the love due to him. Is in darkness until now - Void of Christ, and of all true light.
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.
