Colossians 3:3

For ye are dead - To all hopes of happiness from the present world; and, according to your profession, should feel no more appetite for the things of this life, than he does whose soul is departed into the invisible state.

Your life is hid with Christ in God - Christ is your treasure; and where your treasure is, there is your heart. Christ lives in the bosom of the Father; as your heart is in him, ye also sit in heavenly places with Christ Jesus. Christ is the life of your souls; and as he is hidden in the bosom of the Father, so are ye, who live through and in him.

For ye are dead - Dead to the world; dead to sin; dead to earthly pleasures. On the meaning of the word "dead," see the Romans 6:2 note; Ephesians 2:1 note. The idea of the apostle is, that as Christ became literally dead in the tomb, so we, in virtue of our connection with him, have become dead to sin, to worldly influences, pleasures, and ambition. Or, in other words, we are to be to them as if we were dead, and they had no more influence over us than the things of earth had over him in the grave; Notes, Romans 6:2.

And your life - There is still life. Though dead to one class of objects, you are alive to others. See the sentiment here expressed, explained at large in the notes at Galatians 2:20.

Is hid with Christ in God - The language here is taken probably from treasure which is "hid" or concealed in a place of security; and the idea is, that eternal life is an invaluable jewel or treasure, which is laid up with Christ in heaven where God is. There it is safely deposited. It has this security, that it is with the Redeemer, and that he is in the presence of God; and thus nothing can reach it or take it away. It is not left with us, or intrusted to our keeping - for then it might be lost as we might lose an invaluable jewel; or it might be wrested from us; or we might be defrauded of it; but it is now laid up far out of our sight, and far from the reach of all our enemies, and with one who can "keep that which we have committed to him against that day;" 2 Timothy 1:12. Our eternal life, therefore, is as secure as it could possibly be made. The true condition of the Christian is, that he is "dead" to this world, but that he has immortal life in prospect, and that is secure, being in the holy keeping of his Redeemer, now in the presence of God. From this it follows that he should regard himself as living for heaven.

3:3 For ye are dead - To the things on earth. And your real, spiritual life is hid from the world, and laid up in God, with Christ - Who hath merited, promised, prepared it for us, and gives us the earnest and foretaste of it in our hearts.
