Are Paul's gospel teachings about Christ's death and resurrection found in Jesus's earthly ministry?
No. Paul's gospel concerning Christ's death, burial, and resurrection was not found in Jesus's earthly ministry or in His own words during that time. It was revealed through Paul, the apostle of the Gentiles, by the Holy Spirit, as he preached the cross to the lost.
Les explains that the statements about Christ's death, burial, and resurrection were prompted by the moving of the Holy Spirit through Paul, the apostle of the Gentiles. He points out that you will not find this even in Christ's earthly ministry or any of His own words as He was dealing back there at that time. In 1 Corinthians 1:17, Paul says Christ sent him not to baptize, unlike John the Baptist, who was sent to baptize and preached the baptism of repentance. Paul's mission was to preach the Gospel: that Christ died, was buried, and rose again. The preaching of the cross is foolishness to those who perish, yet it has everything to do with us because God has His controversy with man.
