Charles Spurgeon Commentary 2 Corinthians 8:19-21

"and not only so, but who was also appointed by the churches to travel with us in [the matter of] this grace, which is ministered by us to the glory of the Lord, and [to show] our readiness: Avoiding this, that any man should blame us in [the matter of] this bounty which is ministered by us: for we take thought for things honorable, not only in the sight of the Lord, but also in the sight of men." — 2 Corinthians 8:19-21 (ASV)

Which is administered by us to the glory of the same Lord, and declaration of your ready mind: avoiding this, that no man should blame us in this abundance which is administered by us: providing for honest things, not only in the sight of the Lord, but also in the sight of men.

The apostle is very particular and careful, and in this he sets an example to all of you who have anything to do with any work for God. Do not let it rest on yourselves alone; have others associated with you to share the responsibility, and help you to look after it.
