Last Apostle and his secret

Who is St. Paul?

He was sent by Jesus Christ to preach the gospel especially to
us-Gentiles. The 12 Apostles headed by St Peter were for the
Jews. (Gal. 2:7) That's why St. Paul said that we must rightly divide
the truth (2 Tim 2:15) because, the Bible is a mixture of many
truths or good news; one for the Gentiles and one for the Jews.
The mystery or secret behind the cross was exclusively revealed
to St. Paul (Eph 3:9), and that is; the power of God (Rom 1:16)
unto salvation through the precious blood of His Son. We are
saved by our faith, not of our works; it is God's gift. It is God's
grace; for if it is by works, it's no longer grace (Eph 2:8,9). For
if it's by works of the law; then Christ's death is useless (Gal. 2:21).
St. Paul is the Apostle for our time.
