"The Scripture, foreseeing that God would justify the Gentiles by faith, preached the gospel beforehand to Abraham" (Gal 3:8). "In Him we have redemption through His blood" (Eph 1:7). It is "the mystery which has been hidden from the past ages and generations" (Col 1:26). The Apostle Paul was a steward "of the mysteries of God" (1Co 4:1). He said "we speak God's wisdom in a mystery, the hidden wisdom which God predestined before the ages to our glory" (2:7). It was hidden and God had to reveal it. Paul said "He made known to us the mystery of His will" (Eph 1:9). He said it was "God's grace which was given to me for you; that by revelation there was made known to me the mystery" (3:3). "This grace was given . . . to bring to light what is the administration of the mystery" (:8-9). Paul said "when you read you can understand my insight into the mystery of Christ" (:4). We base our faith on God's revelation. It "was not made known to the sons of men, as it has now been revealed to His holy apostles and prophets in the Spirit" (:5). Paul told the Galatians "that the gospel which was preached by me is not according to man" (Gal 1:11). He said "I received it through a revelation of Jesus Christ" (:12). Furthermore Paul said it was "to reveal His Son in me so that I might preach Him among the Gentiles" (:16).
Paul told the Colossians that "I was made a minister according to the stewardship from God bestowed on me for your benefit" (Col 1:25). The mystery revealed is "Christ in you, the hope of glory" (:27). It is "God's mystery, that is, Christ Himself, in whom are hidden all the treasures of wisdom and knowledge" (Col 2:2-3). Paul said "the mystery is great; but I am speaking with reference to Christ and the church" (Eph 5:32). He prayed that "utterance may be given to me . . . to make known with boldness the mystery of the gospel" (6:19). He also requested that "God may open up to us a door for the word, so that we may speak forth the mystery of Christ" (Col 4:3).
Paul told the Galations "we have believed in Christ Jesus, so that we may be justified by faith in Christ" (Gal 2:16). Therefore "you are all sons of God through faith in Christ Jesus. For all of you who were baptized into Christ have clothed yourselves with Christ" (3:26). Paul explained "'I have been crucified with Christ; and it is no longer I who live, but Christ lives in me'" (2:20). This is the mystery (Col 1:27). "The life which I now live in the flesh I live by faith in the Son of God" (Gal 2:20). We are "those who believe and are saved" (Heb 10:39 NIV).
