From the Word
1 If then ye were raised together with Christ, seek the things that are above, where Christ is, seated on the right hand of God. 2 Set your mind on the things that are above, not on the things that are upon the earth. 3 For ye died, and your life is hid with Christ in God. 4 When Christ, who is our life, shall be manifested, then shall ye also with him be manifested in glory. 5 Put to death therefore your members which are upon the earth: fornication, uncleanness, passion, evil desire, and covetousness, which is idolatry;
Colossians 3:1–5, RSV
Here is comfort for Christians in this earthly life, where their resurrection seems untrue to the world and to their own perceptions, though they receive the doctrine of Christ and apprehend him by faith; where they must contend with sin and infirmities and besides are subject to much affliction and adversity; and where consequently they are extremely sensible of death and terror when they should experience joy and life. In this verse Paul comforts them, showing where to seek and surely apprehend their life. Be of good cheer, he would say, for ye are dead to the worldly life. This life ye must renounce, but in so doing ye make a precious exchange. Dying unto the world is a blessed experience, for which ye will obtain a life far more glorious. Ye are now through Christ’s death redeemed from sin and from death eternal and are made imperishable. Upon you is conferred everlasting glory. But this risen life ye cannot yet perceive in yourselves; ye have it in Christ through faith.
Christ is spoken of as “our life.” This life is certain, though still unrevealed to you, insured to you beyond the power of any one to deprive you of it. By faith in Christ’s life, are ye to be preserved and to obtain victory over the terrors and torments of sin, death and the devil, until that life shall be revealed in you and made manifest to men. In Christ ye surely possess eternal life. Nothing is lacking to a perfect realization except that the veil whereby it is hidden as long as we are in mortal flesh and blood is yet to be removed. Then will eternal life be revealed. Then all worldly, terrestrial things, all sin and death, will be abolished. In every Christian shall be manifest only glory. Christians, believing in Christ and knowing him risen, should comfort themselves with the expectation of living with him in eternal glory.
Saints must, therefore, by a vigorous and unceasing warfare subdue their sinful lusts if they would not lose God’s grace and their faith. To retain the Spirit and the incipient divine life, the Christian must contend with himself. Positive mortification is necessary. And this is the way to mortify sin: it must be perceived with serious displeasure and repented of; and through faith Christ’s forgiveness must be sought and found.
