This study was taught by Clifford McLain in a series from 1982-1983 recorded on cassette tapes converted to digital audio for your benefit. The Sacred Secret study includes 40 lessons and teaches about the body of truth that was given to the apostle Paul to be revealed in Ephesians to the Gentiles. Ephesians opens with "1 Paul, an apostle of Jesus Christ by the will of God, to the saints which are at Ephesus, and to the faithful in Christ Jesus: 2 Grace be to you, and peace, from God our Father, and from the Lord Jesus Christ. 3 Blessed be the God and Father of our Lord Jesus Christ, who hath blessed us with all spiritual blessings in heavenly places in Christ: 4 According as he hath chosen us in him before the foundation of the world, that we should be holy and without blame before him in love: 5 Having predestinated us unto the adoption of children by Jesus Christ to himself, according to the good pleasure of his will, 6 To the praise of the glory of his grace, wherein he hath made us accepted in the beloved." This sacred secret is called the "mystery" in Ephesians 3:9, Colossians 1:25,26 and is specifically addressed to Gentiles for faith obedience. Listen to this study to learn about this sacred secret that has been hidden in God before the foundation of the world and how it was revealed by the Apostle Paul directly to you.
