Now we exhort you, brethren, warn them that are idle, encourage the faint-hearted, support the weak, be patient toward all men.
All Commentaries on 1 Thessalonians 5:14 Go To 1 Thessalonians 5
Augustine of Hippo
AD 430
Of course, even good men can be sick, suffering from that disobedience which is the penalty of a primal disobedience which, therefore, is a wound or weakness in a nature that is good in itself. It is because of this wound that the good who are growing in grace and living by faith during their pilgrimage on earth are given the counsels, “Bear one another’s burdens, and so you will fulfill the law of Christ,” and elsewhere, “We exhort you, brothers, reprove the irregular, comfort the fainthearted, support the weak, be patient toward all men. See that no one renders evil for evil to any man.” … It is in this way that citizens of the City of God are given medicine during their pilgrimage on earth while praying for the peace of their heavenly fatherland. And, of course, the Holy Spirit is operative internally to give healing power to the medicine which is applied externally, for, otherwise, no preaching of the truth is of any avail. Even though God makes use of one of his obedient creatures, as when he speaks in human guise to our ears—whether to the ears of the body or to the kind of ears we have in sleep—it is only by his interior grace that he moves and rules our mind.
