Matthew Henry Commentary 2 Corinthians 9:1-5

"For as touching the ministering to the saints, it is superfluous for me to write to you: for I know your readiness, of which I glory on your behalf to them of Macedonia, that Achaia hath been prepared for a year past; and your zeal hath stirred up very many of them. But I have sent the brethren, that our glorying on your behalf may not be made void in this respect; that, even as I said, ye may be prepared: lest by any means, if there come with me any of Macedonia and find you unprepared, we (that we say not, ye) should be put to shame in this confidence. I thought it necessary therefore to entreat the brethren, that they would go before unto you, and make up beforehand your aforepromised bounty, that the same might be ready as a matter of bounty, and not of extortion." — 2 Corinthians 9:1-5 (ASV)

When we want others to do good, we must act toward them prudently and tenderly, and give them time. Christians should consider what brings honor to their profession of faith, and endeavor to adorn the doctrine of God their Savior in all things. The duty of ministering to the saints is so clear, that it would seem there is no need to exhort Christians to it; yet self-love contends so powerfully against the love of Christ, that it is often necessary to stir up their minds by reminding them.
