Isaiah 53:5 AMP
[5] But He was wounded for our transgressions, He was crushed for our wickedness [our sin, our injustice, our wrongdoing]; The punishment [required] for our well-being fell on Him, And by His stripes (wounds) we are healed.
Long before the actual sacrifice was made, God had all the plans in place. Long before it became a physical reality, God already laid out the plan for the full redemption of man back to Himself. Isaiah prophesied about 600 years before Christ was born in the flesh, so he could not have had any inkling of what was ahead, if God did not reveal it. It is therefore not a surprise that the cross happened. It was not an accident of history that the cross happened. It was all in God's plan, and we can say, with every sense of gratitude, that our lives changed when God put His plan in motion and Jesus consented to be the sacrifice for sin.
Read the verse above, and it would seem that it happened in the past. Isaiah must have been recalling something that had already happened, but as we know, at the time, it had not. From God's perspective, it was already settled. This is the God who calls the things that be not as though they were, and who uses the things that are not, to nullify the things that are, so that no one can boast in His presence. Check out all that Jesus went through, so He could offer the perfect sacrifice for my sin: He was wounded, He was crushed, He was burdened, He was flogged and then hung on a tree. Could any of us have gone through these experiences and remained faithful to the assignment?
For all the experiences He went through, there is an equivalent gain for me. His wounds led to my salvation. His crushing led to my victory and success. His flogging sealed my hope, joy and redemption, as well as my healing. I could not get any of these things by wealth, circle of influence, connections, or anything else. Only the One who made the heaven and the earth could offer that which God could accept as full and final payment for present and even future sin. Reflect on this: for the first and last time, God the Father turned His back on His Son, because of the burden He carried. What a privilege. What a blessing. What joy. What peace.
However, what the verse above also makes clear is that I have now been put on notice. I have no excuse if I miss out on all that God has made available. He has done His pwn part, and He invites me to step into the finished work. What this also tells me is that this work will not be repeated ever again. It is a one-off offer, and valid for this earthly phase. All I can do is only good for this present earthly phase. A day comes soon when I will get the due reward or punishment for my response to what I have been offered. May all the pain that Jesus suffered for me not be in vain. May I have no eternal regrets. God's time of favour is here.
