We can never fight against sin— Jesus Christ conquered that in His redemption of us.

The conflict is waged over turning our natural life into a spiritual life. This is never done easily, nor does God intend that it be so. It is accomplished only through a series of moral choices.

God does not make us holy in the sense that He makes our character holy. He makes us holy in the sense that He has made us innocent before Him. And then we have to turn that innocence into holy character through the moral choices we make.
