I agree that it is dual nature, what you fail to realize is that flesh will still sin and the source of our salvation comes from the righteous life of Jesus and not by our human effort.
And with this I do agree and said as much in the study "Justification".(post #82364)
Those that fall into sin have not learned to walk in the Spirit and have once again been overcome by the flesh which can and does happen, and God does deal with us when this happens.
Yet they are still justified and will stay justified because they have the righteousness of Jesus imputed to them.
And what is the course one should take in this instance?Paul asked:
"What shall we say then? Shall we continue in sin, that grace may abound?God forbid. How shall we, that are dead to sin, live any longer therein?"(Romans 6:1,2)
Which implies we may be in serious trouble if we continue in sin.The writer to the Hebrews speaks of the how God deals with us when in sin and says:
"For whom the Lord loveth he chasteneth, and scourgeth every son whom he receiveth.If ye endure chastening, God dealeth with you as with sons; for what son is he whom the father chasteneth not?But if ye be without chastisement, whereof all are partakers, then are ye bastards, and not sons.Furthermore we have had fathers of our flesh which corrected us, and we gave them reverence: shall we not much rather be in subjection unto the Father of spirits, and live?For they verily for a few days chastened us after their own pleasure; but he for our profit, that we might be partakers of his holiness.Now no chastening for the present seemeth to be joyous, but grievous: nevertheless afterward it yieldeth the peaceable fruit of righteousness unto them which are exercised thereby.Wherefore lift up the hands which hang down, and the feeble knees;
And make straight paths for your feet, lest that which is lame be turned out of the way; but let it rather be healed.Follow peace with all men, and holiness, without which no man shall see the Lord:"
John also writes:
"My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous:And he is the propitiation for our sins: and not for ours only, but also for the sins of the whole world."(I John 2:1,2)
What if we continue in sin and do not fully repent?What if we do not make straight paths for our feet but are turned out of the way?And isn't the injunction by John,for us not to sin the,imperative of the statement above rather than the fact that we have an advocate who can remove them when we do?
