Let brotherly love continue.
I. ESPECIALLY NECESSARY AT THE PRESENT SEASON. It was a time of trial from outside. Brothers needed to be brotherly, helping one another. We cannot expect anything from strangers, and must be ready even for their hostility. But we must do everything to guard against alienation amongst friends at a time when the closest union will be serviceable.
II. THE COUNSEL NECESSARY BECAUSE SELF-REGARD IS SUCH A SUBTLE SIN. Carnal views of the kingdom of heaven, such as seem to have been prevalent among these Hebrew Christians, inevitably led to each one of them thinking what in the expected glorious state of things he would get for himself. So it was among the disciples of Jesus. They disputed who should be greatest. There was even intrigue to get promise of the principal places. Christians need to be ever on their guard lest any feeling get dominion in their hearts hostile to the good of the whole body.
III. WE ARE REMINDED OF ABIDING THINGS THAT DEPEND ON OUR OWN DISPOSITION. The writer has just been referring to things that can be shaken and removed, and things that cannot be shaken. These are things that God deals with by his power. But the continuance of some things depends on whether we will have them continue. Whether brotherliness shall be a deep and abiding thing depends on the state of our hearts.
IV. CONTINUAL REMEMBRANCE OF THE REAL RELATION OF EVERY CHRISTIAN TO EVERY OTHER CHRISTIAN. By the same Spirit we are all born again, and therefore members of the same Divine family. Each of us, therefore, is under certain obligations; each of us may prefer certain claims. But there can be no proper treatment either of the obligations or the claims unless there be real affection underneath. It is in the spiritual sphere as in the natural; the mere relation may only irritate unless there be the feelings that properly belong to the relation. - Y.
