The Twofold Purpose of The Mystery - Part 4. The body of truth called “The Mystery” is really our great commission for the believers of this age. Much like the commission given to the disciples in Matthew 28:19-20, our commission is given in Ephesians 3:9. This is what God has given us with this particular fellowship which is part of a particular administration. Christ Jesus is the fullness of God and we a made a part of His calling in Christ. The Jew has nothing today that makes him distinctive in God’s eyes. There are two things that make this truth distinctively to you (2U).
