Charles Spurgeon Commentary 2 Corinthians 6:3-4

"giving no occasion of stumbling in anything, that our ministration be not blamed; but in everything commending ourselves, as ministers of God, in much patience, in afflictions, in necessities, in distresses," — 2 Corinthians 6:3-4 (ASV)

Giving no offense in anything, that the ministry be not blamed: but in all things approving ourselves as the ministers of God,

As those early servants of the Lord really did.
