Jesus Did What We Could Not Do.
John 11:43-44 NKJV
Now when He had said these things, He cried with a loud voice, “Lazarus, come forth!”  And he who had died came out bound hand and foot with graveclothes, and his face was wrapped with a cloth. Jesus said to them, “Loose him, and let him go.”
When Jesus raised Lazarus from the dead He told the bystanders to, “Loose him and let him go.”
Since Jesus raised the dead, why did He not loose the grave clothes too ?
I don’t know. But it has been suggested that Jesus did what they could not do, and expected them to do what they could. It sounds reasonable.
That is what happened in the provision for our forgiveness of sin.
We can obey the gospel and take advantage of what Jesus has done.
But we could never do what Jesus did. JESUS provided the cleansing agent of our sin stained souls; His precious blood. Only His sacrifice could produce the forgiveness of sins.
We merit nothing when we obey the gospel. But we reach His Blood and thereby are washed clean and loosed from the grave clothes of sin and death.
Romans 6:1-14 NKJV
What shall we say then? Shall we continue in sin that grace may abound?  Certainly not! How shall we who died to sin live any longer in it?  Or do you not know that as many of us as were baptized into Christ Jesus were baptized into His death?  Therefore we were buried with Him through baptism into death, that just as Christ was raised from the dead by the glory of the Father, even so we also should walk in newness of life.  For if we have been united together in the likeness of His death, certainly we also shall be in the likeness of His resurrection,  knowing this, that our old man was crucified with Him, that the body of sin might be done away with, that we should no longer be slaves of sin.  For he who has died has been freed from sin.  Now if we died with Christ, we believe that we shall also live with Him,  knowing that Christ, having been raised from the dead, dies no more. Death no longer has dominion over Him.  For the death that He died, He died to sin once for all; but the life that He lives, He lives to God.  Likewise you also, reckon yourselves to be dead indeed to sin, but alive to God in Christ Jesus our Lord.  Therefore do not let sin reign in your mortal body, that you should obey it in its lusts.  And do not present your members as instruments of unrighteousness to sin, but present yourselves to God as being alive from the dead, and your members as instruments of righteousness to God.  For sin shall not have dominion over you, for you are not under law but under grace.
