2Tim. 2.8 Risen from the dead = The constant theme of Paul's preaching. Seed of David = Is he stressing his humanity, OR his lineage as evidence of Messiahship, or both. According to my gospel = Comp. Romans 2:16; Romans 16:25, and see 1 Corinthians 15:1; 2 Corinthians 11:7; Galatians 1:11; Galatians 2:2; 1 Timothy 1:11. Some see this as a reference to the gospel penned by Luke. Just at Mark is said to have presented Peter's gospel, so Luke is said by early writers (Jerome, etc) to have penned Paul's gospel .
