Romans 1:16

I am not ashamed of the gospel, for it is the power of God for salvation (from His wrath and punishment) to everyone who believes (in Christ as Savior), to the Jew first and also to the Greek.

At one time in his walk with God, Saul, before he became Paul, was persecuting Christians for the gospel.  What a difference the grace and love of God made in his life.   Paul’s life was radically changed when he met Jesus on the road to Damascus in a new direction of faith and hope in Jesus, and Paul shared his new faith.  We are the extension of Paul now, called to share our faith and the story of our radically changed lives.
