1 John 3:14 - Clarke's commentary and critical notes on the Bible

We know that we have passed from death unto life, because we love the brethren. He that loveth not his brother abideth in death. 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, Colossians 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.
