2 Corinthians 4:13-15 (NLT)
13 But we continue to preach because we have the same kind of faith the psalmist had when he said, “I believed in God, so I spoke.” 14 We know that God, who raised the Lord Jesus, will also raise us with Jesus and present us to himself together with you. 15 All of this is for your benefit. And as God’s grace reaches more and more people, there will be great thanksgiving, and God will receive more and more glory.

The Apostle Paul refers to Kind David when he said, “I have believed, and therefore have I spoken”. It is faith, belief in Christ that keeps them motivated to tell others about The Savior. They know that even through their suffering their work is a benefit for all. For as God’s word reaches people and more people accept Christ as savior there will be great thanksgiving and God will be glorified.

John Piper is the Pastor for Preaching at Bethlehem Baptist Church in Minneapolis, Minnesota. He grew up in Greenville, South Carolina, and studied at Wheaton College, where he first sensed God's call to enter the ministry. He is quoted as saying, “What shall we be known for? Let it be that we are willing to die for Christ and, even more, that we are willing to live for him in loving his people—and his enemies.” Secondly, “God is most glorified in me when I am most satisfied in Him. This is the motor that drives my ministry as Pastor. It affects everything I do.” We must go beyond our faith and find satisfaction in what God has given us. We must let Christ rule in our heart and be our motivation to reach out to others. And as others find Christ through our work God will be glorified and praises of thanksgiving will ring out in heaven.
