Now we know of course that all of the decay is the result of sin and the curse, and in this verse we see a glorious parallel. From the moment of birth, we are under sin: "For I was born a sinner—yes, from the moment my mother conceived me (Psalm 51:5 NLT). That means from the moment of conception we are "sold under sin" and we are corrupt in mind and body, we are "accustomed to doing evil" and on the inevitable decline to dissipation, depravity and damnation.
I have been reading in First John, and I was really struck by this particular idea from the third chapter:
28 And now, little children, abide in Him, that when He appears, we may have
confidence and not be ashamed before Him at His coming.29 If you know that He is
righteous, you know that everyone who practices righteousness is born of
Behold what manner of love the Father has bestowed on us, that
we should be called children of God! Therefore the world does not know us,
because it did not know Him.2 Beloved, now we are children of God; and it has
not yet been revealed what we shall be, but we know that when He is revealed, we
shall be like Him, for we shall see Him as He is.3 And everyone who has this
hope in Him purifies himself, just as He is pure (1 John 2:28-3:3 NKJV).
The miracle of Salvation is being "born again"; "whoever believes that Jesus is the Christ is born of God" (italics added I Jn. 5:1). From the moment of our "New Birth" we are no longer on the trajectory and inevitable, we will become "like Him". We are becoming, not dying, our spiritual muscles are strengthening, our consciences are being built into a nervous system that overcomes sin, minds being sharpened in the truth and spiritual life, the abundant life, the joyful life is more and more ours! Now "it has not yet being revealed" exactly what this will look like in the end, just as none of us knows how far we'll age, or whether we'll grow frail in this way, or that, we know it is inevitable that we will die. But in Christ, we have this hope, that although we don't know how exactly we'll look, or to what extent we shall see it in this life, but we will live eternally free from sin!
