16:1-9 The good examples of other Christians and churches should rouse us. It is good to lay up in store for good uses. Those who are rich in this world, should be rich in good works, 1Ti 6:17,18. The diligent hand will not make rich, without the Divine blessing, Pr 10:4,22. And what more proper to stir us up to charity to the people and children of God, than to look at all we have as his gift? Works of mercy are real fruits of true love to God, and are therefore proper services on his own day. Ministers are doing their proper business, when putting forward, or helping works of charity. The heart of a Christian minister must be towards the people among whom he has laboured long, and with success. All our purposes must be made with submission to the Divine providence, Jas 4:15. Adversaries and opposition do not break the spirits of faithful and successful ministers, but warm their zeal, and inspire them with fresh courage. A faithful minister is more discouraged by the hardness of his hearers' hearts, and the backslidings of professors, than by the enemies' attempts.

many adversaries—who would block up the way and prevent us from entering the open door. Not here false teachers, but open adversaries: both Jews and heathen. After Paul, by his now long-continued labors at Ephesus, had produced effects which threatened the interests of those whose gains were derived from idolatry, "many adversaries" arose (Ac 19:9-23). Where great good is, there evil is sure to start up as its antagonist.
