1 John 3:14

Verse 14. We know that we have passed from death.

While we are hated by the world, this should not be regarded by us, since we know that we have passed away from a state the final end of which is eternal death, into a state the end of which is life eternal.

Because we love the brethren.

The reason is here given for the knowledge we possess of having passed from death into life. Love of the brethren is the test. This is the surest mark by which we can know our state. This disposition is enjoined by our holy religion. There is no danger that the humble disciple, because of the high encomiums bestowed on this virtue by the sacred Writers, shall ever conclude that love of the brethren exhausts all of his Christian duties. He knows better; he has always before him the example of his Master and his blessed teachings, and these unmistakably require at his hands many other duties which embrace those not of the brotherhood.

Abideth in death.

The test by which one may know that the hope of eternal life is not entertained. When one hates his brother, the test is sure. Such an one is still under the condemnation of death; in other words, he is in that state which will ultimate in eternal death.
