In Colossians 3:3, the apostle Paul wrote to believers in these words, "For you died, and your life is hidden with God in Christ." In the Greek speaking world of the New Testament times, those dead and buried were said to be hidden in the earth. The apostle refers to believers as dead and buried, or hidden with Christ in God. Believers are dead to the old life, buried in baptism, and raised to new life in Christ.
Christ is hidden to the eyes of men, but raised from the dead. He ascended into heaven, "where Christ is sitting at the right hand of God" (Col. 3:1). He is there for every believer, as our great High Priest, and only mediator between God and man. He ever lives to make intercession for us according to the Father's will.
Because your life as a believer is hidden with Christ in God, you have a new mindset. Now your mind is focused beyond earthly things only. "Set your mind on things above, not on things on the earth" (Col. 3:2). You now focus on the things of God, with an eternal perspective. You are concerned about the will of God and service to Christ.
While all believers are hidden with Christ in God, the day is coming when we shall be revealed in glory with Christ. What a day that will be! "When Christ who is our life appears, then you also will appear with Him in glory" (Col. 3:4). It is in glory that we shall receive a glorified body, fashioned after the likeness of our Lord Jesus Christ (1 Cor. 15:42-43).
