19 And not only so, but he was marked out by the churches to go with us in the grace of this giving which we have undertaken to the glory of the Lord and to make clear that our mind was ready: 20 And so that no man might be able to say anything against us in the business of this giving which has been put into our hands: 21 For the business has been so ordered by us as to have the approval, not only of the Lord, but of men.

Commentary on 2 Corinthians 8:16-24
(Read 2 Corinthians 8:16-24)
The apostle commends the brethren sent to collect their charity, that it might be known who they were, and how safely they might be trusted. It is the duty of all Christians to act prudently; to hinder, as far as we can, all unjust suspicions. It is needful, in the first place, to act uprightly in the sight of God, but things honest in the sight of men should also be attended to. A clear character, as well as a pure conscience, is requisite for usefulness. They brought glory to Christ as instruments, and had obtained honour from Christ to be counted faithful, and employed in his service. The good opinion others have of us, should be an argument with us to do well.
