Romans 8:13

for if ye live after the flesh, ye must die; but if by the Spirit ye put to death the deeds of the body, ye shall live. [So then, brethren, because of the relation which we sustain to Christ, and because of the opposite effects of living fleshly and spiritual lives, we, though free from the law, are under no obligation to be lawless, and to live after the flesh: for if ye so live ye must pay the penalty of such a course by dying; but if, by the exercise of your will, and the aid of the Holy Spirit, ye put an end to the sinful practices of your fleshly nature, ye shall live. The testimony of Christian experience is that the aid of the Holy Spirit, though real and effectual, is not so obtrusive as to enable the one aided to take sensible notice of it. To all appearance and sensation the victory over flesh is entirely the Christian's own, and he recognizes the aid of the Spirit, not because his burdens are sensibly lightened, but because of the fact that in his efforts to do right he now succeeds where lately he failed. The success, moreover, though habitual, is not invariable, for invariable victory over temptation breeds self-consciousness and self-righteousness, and other sins perhaps more dangerous than the ordinary lusts of the flesh.]
