God is withholding His pleasure, He is cutting His people off. Rather than the curse coming directly from God, we are cursed with the curse itself that results in the natural course that the sin takes. Like Pogo, we have met the enemy and it is us. We must, of course, initially have forgiveness of sins, we must have justification, we must have peace with God. The saints move on to something more and that is the constant effort to walk in the spirit, free oneself from sin and take on the holy and sanctified nature.
Sin first exists in the mind and our heart's desire from an external or internal stimulus.
We make provision for sin when we do not clean up what is around us. The temptation involved gives us space to make the choice to entertain it and give in or to resist before it is an overt act. Sin is therefore potentiated weakness or potentiated defiance. Victory is sweet. The early church did not command very much abstinence, loving God, loving others and walking in the spirit is generally sufficient for us.
