You know, brothers and sisters, that our visit to you was not without results. We had previously suffered and been treated outrageously in Philippi, as you know, but with the help of our God we dared to tell you his gospel in the face of strong opposition. 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 those approved by God to be entrusted with the gospel. We are not trying to please people 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 people, not from you or anyone else, even though as apostles of Christ we could have asserted our authority. Instead, we were like young children among you. Just as a nursing mother cares for her children, so we cared for you. Because we loved you so much, we were delighted to share with you not only the gospel of God but our lives as well.1 Thessalonians 2:1-8 (NIV)
The Gospel has been entrusted to us and in order to share it we must pray for God-given boldness. The Gospel is to be shared in sincerity and in fullness from a heart of love and from a desire to serve and praise Christ.
