Our New Life Source
Colossians 3:3 (ESV) … “For you have died, and your life is hidden with Christ in God.”
The question may well be asked: If I died with Christ, how do I continue to live? Paul’s answer was that Christians’ lives are “hidden with Christ in God.” Although some may understand the point of this statement to be the safety of believers, Paul used it to refer to the source of believers’ lives.
The new life source, that which sustains Christians, is Christ. Paul clearly stated as much in the next verse. Just as Christ is now hidden from the eyes of the world, the Christian’s life in Christ is also hidden. Christians appear as dead to the things of the world, but very much alive with a source of life that goes beyond this world and what it can provide. The new life is Christ. His life energizes Christians, enabling them to be and do what they should. The life Christ provides encourages believers to seek the things identified with that life.
