Notable theological differences exist between the teachings of Jesus and Paul.
To the nation of Israel, Jesus ministered on earth. To the body of Christ, the Church, Christians, Jesus ministers from heaven.
Jesus was a minister to Israel to fulfill the covenants and the prophetic kingdom program. Paul taught doctrines he received from the risen, ascended, glorified, heavenly Christ.
Jesus ministered under the Law of Moses. The risen Lord commissioned Paul as a minister of grace.
Under Law, one forgave in order to be forgiven. Under grace we forgive because we have been forgiven.
The Law of Moses said, βDo.β When one βdidβ he received Godβs blessing. Paul declared that the Law was βholy, righteous, and goodβ (Romans 7.12) but that believers of his gospel were under a new administration which he received from the Lord. That new administration was direction and guidance of the Holy Spirit under grace as God commissioned Paul as the minister of the βgospel of the grace of Godβ (Acts 20.24).
What a difference!
