Romans 6:5

For if we have become united with him in the likeness of his death, we shall be also in the likeness of his resurrection [The apostle here meets the cavil of some objector who supposes that we might die to sin in baptism, and still be under no obligation to retrain from it after baptism. The answer is, that we can not be united to Christ in one part of the ordinance (the burial, or immersion), and severed from him in the other part (the resurrection, or emersion). If, says he, we have become united with Christ in that part of the ordinance wherein he died to destroy the power of sin, it is morally certain that we shall continue to be united with him in that other part, wherein he rose to lead a new life--a life no longer confined to earth and its sinful environment, but one far removed from the realm of wickedness in the courts of the Father. If, therefore, we died with him to sin, we must also rise with him to lead a new life in the (to us) new kingdom of God, which looks forward to the enjoyment of those very changes wrought in Christ by his ascension. Neither in dying nor living do we accomplish the actual in the ordinance. We are not actually united with Christ in death, but in an ordinance which resembles it. We do not actually die as to sin, as did Christ; but we do profess a likeness to his death. We do not rise, as did he, to a glorified life, but we strive to maintain a similitude, or likeness, to it. When at last, in a real death and resurrection, Christ actually unites us with himself, we shall indeed be dead to sin, and alive to righteousness; for there is no sin among the immortals, and there shall be no lack of perfection in those who have been changed into Christ's image];
