No one will walk according to the Spirit rather than the flesh unless they repent. God is not going to force me to walk according to the Spirit against my will. I must make a conscious decision to turn from the works of the flesh unto Christ and His righteousness which He will produce in me through the indwelling of His Spirit.
A man cannot be born again apart from surrendering his life to the Lord; and a man will not continue to live spiritually, once born again, unless he continues to mortify the deeds of the body through the Spirit, and does not live according to his flesh...being born again means a changed heart...and life! There is a practical righteousness produced in the person who is saved...and God will not produce this against a man's will...he must repent of his sins in order to receive this righteousness.
My premise being that according to
Romans 8:12-13 a man's spiritual life or death depends on whether he walks according to the flesh or whether he walks according to the Spirit. And the question of,
can a man be justified who is spiritually dead? Because if he can not be, then walking according to the flesh will have an effect on whether I am justified or not. Because if I live according to the flesh, I will become spiritually dead, and therefore if I cannot be justified as one who is spiritually dead, then walking in the flesh will mean that I am not justified before the Lord, if I become spiritually dead because of walking in the flesh; because I cannot be justified as one who is spiritually dead.
