13:16-21 We must, according to our power, give to the necessities of the souls and bodies of men: God will accept these offerings with pleasure, and will accept and bless the offerers through Christ. The apostle then states what is their duty to living ministers; to obey and submit to them, so far as is agreeable to the mind and will of God, made known in his word. Christians must not think themselves too wise, too good, or too great, to learn. The people must search the Scriptures, and so far as the ministers teach according to that rule, they ought to receive their instructions as the word of God, which works in those that believe. It is the interest of hearers, that the account their ministers give of them may be with joy, and not with grief. Faithful ministers deliver their own souls, but the ruin of a fruitless and faithless people will be upon their own heads. The more earnestly the people pray for their ministers, the more benefit they may expect from their ministry. A good conscience has respect to all God's commands, and all our duty. Those who have this good conscience, yet need the prayers of others. When ministers come to a people who pray for them, they come with greater satisfaction to themselves, and success to the people. We should seek all our mercies by prayer. God is the God of peace, fully reconciled to believers; who has made a way for peace and reconciliation between himself and sinners, and who loves peace on earth, especially in his churches. He is the Author of spiritual peace in the hearts and consciences of his people. How firm a covenant is that which has its foundation in the blood of the Son of God! The perfecting of the saints in every good work, is the great thing desired by them, and for them; and that they may at length be fitted for the employment and happiness of heaven. There is no good thing wrought in us, but it is the work of God. And no good thing is wrought in us by God, but through Christ, for his sake and by his Spirit.

18. Pray for us—Paul usually requests the Church's intercessions for him in closing his Epistles, just as he begins with assuring them of his having them at heart in his prayers (but in this Epistle not till Heb 13:20, 21), Ro 15:30. "Us," includes both himself and his companions; he passes to himself alone, Heb 13:19.

we trust we have a good conscience—in spite of your former jealousies, and the charges of my Jewish enemies at Jerusalem, which have been the occasion of my imprisonment at Rome. In refutation of the Jews' aspersions, he asserts in the same language as here his own conscientiousness before God and man, Ac 23:1-3; 24:16, 20, 21 (wherein he virtually implies that his reply to Ananias was not sinful impatience; for, indeed, it was a prophecy which he was inspired at the moment to utter, and which was fulfilled soon after).

we trust—Greek, "we are persuaded," in the oldest manuscripts. Good conscience produces confidence, where the Holy Spirit rules the conscience (Ro 9:1).

honestly—"in a good way." The same Greek word as "good conscience." Literally, "rightly," "becomingly."
