Verse 8. - Now if we died with Christ, we believe that we shall also live with him; i.e. as explained with regard to the future ἐσόμεθα under ver. 5. The explanation there given accounts for the phrase here, πιστεύομεν ὅτι, without its being necessary to refer our living with Christ exclusively to the future resurrection. For the continuance of God's vivifying grace during life after baptism is a subject of belief.
6:3-10 Baptism teaches the necessity of dying to sin, and being as it were buried from all ungodly and unholy pursuits, and of rising to walk with God in newness of life. Unholy professors may have had the outward sign of a death unto sin, and a new birth unto righteousness, but they never passed from the family of Satan to that of God. The corrupt nature, called the old man, because derived from our first father Adam, is crucified with Christ, in every true believer, by the grace derived from the cross. It is weakened and in a dying state, though it yet struggles for life, and even for victory. But the whole body of sin, whatever is not according to the holy law of God, must be done away, so that the believer may no more be the slave of sin, but live to God, and find happiness in his service.
Now if we be dead with Christ,.... This does not imply any doubt about it, but is rather a taking it for granted: seeing we are dead with Christ by union with him, as our head and representative, and by communion with him in the benefits of his death, and being planted together in the likeness of it; or being dead to the law, sin, and the world, through the virtue and efficacy of Christ's death:
we believe that we shall also live with him; not only a life of justification by faith in his righteousness; and a life of sanctification from him, and to his glory; the continuance of which, and a perseverance in it, are firmly believed; but a life of glory and happiness with him hereafter, both in the new Jerusalem, in the new heavens, and new earth, in the glorious state of the church on earth, and in heaven to all eternity; where they shall be personally and visibly with him, in soul and body, and shall live in the most intimate and uninterrupted communion with him, enjoying the highest pleasure, and the most consummate happiness; and are therefore under the greatest obligation, whilst here on earth, to live, not in sin, but to righteousness, and to his praise and glory; with whom they are now dead to sin, and with whom they not only hope, but believe they shall live throughout the endless ages of eternity.
