For the appeal we make does not spring from error or impure motives, nor are we trying to trick you. On the contrary, we speak as men approved by God to be entrusted with the gospel. We are not trying to please men but God, who tests our hearts. You know we never used flattery, nor did we put on a mask to cover up greed -- God is our witness. We were not looking for praise from men, not from you or anyone else.
1 Thessalonians 2:3-6 (NIV)
