Beginning in verse 8 of chapter 43 God proposes a challenge to the worshippers of idols to offer valid proofs of the existence of their gods. He asks them for witnesses. He asks them for testimony. There is none to be had. In verse 10 God's own people are summoned to "give a witness" to His Divine character and deeds. If you know Him, you realize that's not a very hard request. In the latter part of the verse the Messiah, that Chosen Servant, appears as the star witness. His testimony is given "in order that you may know and believe Me, and understand that I am He."
Yet God, who rightly despises our sin, does not treat us as our sins deserve. Instead, in amazing mercy, He sends His Chosen Servant - the spotless Lamb of God - to live the life we could not live (a sinless one), to die the death we deserved to die (a retributive one), and to rise again on the third day that we would rise again on the last day! "But now Christ has been raised from the dead, the first fruits of those who are asleep. For since by a man came death, by a man also came the resurrection of the dead. For as in Adam all die, so also in Christ all shall be made alive." (1 Co 15:20-22)
My head shakes in disbelief, yet my very life is a testimony of the reality of these wonderful words. My sins were as scarlett but He has washed me white as snow! I am a new creature in Christ, the old has gone the new has come. He no longer calls me a child of wrath but has adopted me as a child of God! The Lord Jesus Christ has wiped my slate clean!
"Thy works, not mine, O Christ, speak gladness to this heart;they tell me all is done; they bid my fear depart.Thy pains, not mine, O Christ, upon the shameful tree,have paid the law's full price and purchased peace for me.Thy cross, not mine, O Christ, has borne the awful loadof sins that none in heav'n nor earth could bear but God.Thy righteousnesss, O Christ, alone can cover me:no righteousness avails save that which is of Thee.To whom, but Thee,who canst alone for sin atone, Lord, shall I flee?"(Horatius Bonar, 1857)."What can wash away my sin? Nothing but the blood of Jesus." (Robert Lowery, 1876).
I am saved not to bring glory to myself but to bring glory to the God who has so marvelously saved me from the pit that my thoughts and actions deserve. Our chief end is to glorify God and to enjoy Him forever. That is why He created us and even more specifically, that is why He saved us. The more I find myself conscientiously seeking to glorify Him, the more I find myself consistently enjoying Him. It's a good place to be!
"Arise, my soul arise, shake off your guilty fears; the bleeding Sacrifice in my behalf appears: before the throne my Surety stands, before the throne my Surety stands, my name is written on His hands." (Charles Wesley, 1742).
"And when you were dead in your transgressions and the uncircumcision of your flesh, He made you alive together with Him, having forgiven us all our transgressions, having cancelled out the certificate of debt consisiting of decrees against us and which was hostile to us; and He has taken it out of the way having nailed it to the cross." (Col 2:13-14).
I am now a debtor to mercy alone.
Here is the glorious blessing of the gospel to us - "I, even I, am the one who wipes away your transgressions for my own sake; and I will not remember your sins."
