What does Colossians 1:27 mean?
The "mystery" of Christ mentioned in the previous verse was both for Jews and Gentiles. In addition to mystery, Paul here notes God's sovereignty, which is His perfect and all-encompassing knowledge and control. The revelation came only when God chose to make it happen. This mystery was "great" both in content and impact among the Gentiles, including to the Colossian believers.The glory of this mystery "is Christ in you, the hope of glory." Christ came to earth and also now lives in those who believe. Interestingly, this is the one place in Paul's letters he uses the explicit phrasing of Christ "in you." He seeks to make the gospel message very personal for these Colossian Christians, whom he has never personally met. With Christ in you, as a saved believer, you have the "hope of glory." In other words, a believer can be confident of eternity with Christ in heaven when he or she knows Christ is already in them now.
