Colossians 3:3

For ye are dead. Literally, “For you died,” that is, symbolically, in baptism (see on Romans 6:2-4). Death precedes the new life. There is a clear distinction between the unregenerate and the regenerate nature. This spiritual death of which Paul speaks is the result of the complete surrender of the human will to God through faith in Christ.

Hid with Christ. The form of the Greek verb indicates that the act of hiding was complete and that its effect continues on to the present. The life is still hidden. The life here spoken of is that which the believer receives when he accepts Christ. Jesus said, “He that believeth on the Son hath everlasting life” (John 3:36). It is his now, and will be translated into glorious immortality at the second coming of Christ (see on John 8:51).
