"Come now, and let us reason together, saith the Lord: though your sins be as scarlet, they shall be as white as snow; though they be red like crimson, they shall be as wool." (Isaiah 1:18)
 Did you know that your Heavenly Father desires to reason with you because  he is a reasonable God, and our faith is a reasonable faith, based on sound evidence. It is not a credulous faith like that of the evolutionist who blindly believes either in the god of chance or in some sort of cosmic consciousness.
  "Be ready always to give an answer [that is, an apologetic, a reasoned defense of our faith] to every man that asketh you a reason of the hope that is in you with meekness and fear" (1 Peter 3:15).

But how can it be reasonable that one whose deeds have been crimson with sin could ever be made "white as snow"? That in itself is not humanly possible and that is exactly why only God himself could pay the sinners debt ! .
 "the things which are impossible with men are possible with God" (Luke 18:27). What seems incredible to human wisdom is altogether reasonable to the Almighty, for all things are possible for He who created both the heavens and the earth and all that is upon it.. He is God and God all by Himself so there not is impossible for him. "Because the foolishness of God is wiser than men; and the weakness of God is stronger than men"
(1 Corinthians 1:25).

This divine wisdom is centered in the sacrificial death and victorious resurrection of Christ, our Redeemer, who "loved us, and washed us from our sins in his own blood" (Revelation 1:5). As a result, now our "reasonable service" to Him is for each of us to offer ourselves to Him as "a living sacrifice" (Romans 12:1).
