What happens or perhaps I should say what is it that SHOULD happen following the gracious forgiveness granted to us by our Savior? I have referred to this 'happening' as metamorphosis in my book From Faith to Faith, but it is more commonly called transformation and refers to the struggle each of us must assume in order to move from the nature of a physical body to a spiritual nature as possessed by God. The new body will be granted when we have completed our life on this earth and hear the Father say "Enter in good and faithful servant." I often forget that the weapons used in my spiritual quest are not of the flesh, but divine. God Himself provided for my victory through the death of His Son, but before victory, comes struggle and it is important to remember that I (we) are not alone. Forgiveness is a part of me now, a constant as the Holy Spirit dwells within, teaching, guiding and comforting in times of sorrow. At some point I realized though Satan is always by my side, tempting me, laying traps for me, taking every advantage he possibly can, he cannot MAKE me do his will. He would if he could, but he doesn't have the power. He, too wants to dwell within me as he wants to be my guide me in wickedness, in order to form my nature in the likeness of his.
Now this is what is so exciting! In spite of the ugliness that dwells within us as the essence and likeness of Satan, when we accept God's forgiveness, He doesn't see that likeness any more. When He looks at us and in us, what He sees is the purity of cleanliness. He knows our struggle, He knows our desire to be cleansed and He has given us the Spirit to guide us. Let me sum it up in a few very important words. This quotation is by Oswald Chambers:
"God does not make us holy in the sense that He made our character holy.
He makes us holy in the sense that He has made us innocent before Him.
We, then, must turn that innocence into holy character through the
moral choices we make."
