Sermon Bible Commentary
Proverbs 13:20
I. Of all the external circumstances which mould our life and character, our daily companionship may be said to be among the most potent, and the Bible utterances are very strong on this subject. Sometimes they dwell specially on the causes that draw men together, assuming that like chooses like, and that a man may in fact be known by his associates. But more frequently the texts warn us rather of the consequences of intimacy than of the causes of it. They warn or exhort about companionship because we become, as they assume, what our companions are; because men who live together in close contact and communion mould each other, as iron sharpeneth iron.
II. It is probable, indeed, that we should all direct our life, and choose our companionship, more carefully if we duly considered the long results of these things; if we remembered that in moral relations, as in other matters, it is not easy to start afresh when we please and unencumbered. Friendships are two-edged tools, which may open up for you the way to life or the way to death.
III. There is no more certain support to the weak or the young than the feeling of nearness to some friend whom they know to be strong and pure, earnest for what is right and a hater of evil. Our companionship with such an one is like living continually in a pure and healthy pasture, and as the nearest earthly resemblance to walking with God in Christ, as we hope in our perfection to walk with Him hereafter. These are the true servants of Christ, and they only have the promise of the life that now is and of that which is to come.
