For Paul:
- The gospel = Christ crucified and risen.
- Salvation = received by grace through faith, not by works of the Law.
- The Spirit = given to those who believe (Galatians 3:2).
His faith is in the risen Lord Jesus as the Son of God and in the Father who raised Him, confessing:
- One God, the Father (1 Corinthians 8:6).
- One Lord, Jesus Christ (same verse).
