{12} And I am sure that, when I come unto you, I shall come in the fulness of the blessing of the gospel of Christ.

(12) He promises them through the blessing of God, not to come empty to them: and requiring of them the duty of prayers, he shows what thing we ought mainly to rest upon in all difficulties and adversities.

People's New Testament

15:29 I am sure that, when I come unto you. He assures them that his coming will be full of blessing to them in Christ. Godet says, with force:

Would a forger of this epistle, in the second century, have drawn a picture of the future so opposite to the way in which things really came to pass?''

These allusions to his future movements are positive proof that this was written before Paul was a prisoner.

Jamieson-Fausset-Brown Bible Commentary

29. And I am sure-"I know"

that . I shall come in the fulness of the blessing of Christ-Such, beyond all doubts, is the true reading, the words "of the gospel" being in hardly any manuscripts of antiquity and authority. Nor was the apostle mistaken in this confidence, though his visit to Rome was in very different circumstances from what he expected. See Ac 28:16-31.

Matthew Henry's Concise Commentary

15:22-29 The apostle sought the things of Christ more than his own will, and would not leave his work of planting churches to go to Rome. It concerns all to do that first which is most needful. We must not take it ill if our friends prefer work which is pleasing to God, before visits and compliments, which may please us. It is justly expected from all Christians, that they should promote every good work, especially that blessed work, the conversion of souls. Christian society is a heaven upon earth, an earnest of our gathering together unto Christ at the great day. Yet it is but partial, compared with our communion with Christ; for that only will satisfy the soul. The apostle was going to Jerusalem, as the messenger of charity. God loves a cheerful giver. Every thing that passes between Christians should be a proof and instance of the union they have in Jesus Christ. The Gentiles received the gospel of salvation from the Jews; therefore were bound to minister to them in what was needed for the body. Concerning what he expected from them he speaks doubtfully; but concerning what he expected from God he speaks confidently. We cannot expect too little from man, nor too much from God. And how delightful and advantageous it is to have the gospel with the fulness of its blessings! What wonderful and happy effects does it produce, when attended with the power of the Spirit!
