The source for finding the gospel is God's Word. While found in many places, we are referring to the book of Romans, (Chapter 1-4). The first part of this gospel Paul speaks about is the wrath of God revealed from heaven. The second part is man's problem... he's rebelled against God. The third part of the gospel is God's solution to humanity's sin... the sacrificial death and resurrection of Jesus Christ. And fourth, the salvation GOD has provided (his perfect plan) which comes through faith in Jesus Christ and it is for all who believe. (3:22 ) And we find this recurring theme throughout the New Testament. God. Man. Christ. Response.
