What believer would deny what was done on the cross? What believer would belittle what was accomplished for us on the tree that was a curse? I would have to say, no true believer would. Not one person who puts their hope in Christ would ever diminish the sacrifice made and the accomplishments made on our behalf by God.
Partly because we acknowledge the work that has been accomplished and mostly because Jesus said, “It is finished” we assume that there is nothing left to be done. But there is more than just sitting on the porch swing drinking Country Time lemonade ahead when it comes to the finished work of God.
Since everyone has a reference of everything being finished at the cross, how many of us know of the scripture that speaks of a great work, that God has put in motion and know the day it will be finished? There is something so long in the coming that the prophets talked of it. To shock many of us, this was not finished at the cross. It was determined to be accomplished at a future date.
But in the days of the voice of the seventh angel, when he shall begin to sound, the mystery of God should be finished, as he hath declared to his servants the prophets.
There is some great event that is still waiting to be accomplished. Something that God has spoken to the prophets and it will be done just as He has revealed to His servants. There is something held out in scripture that is not finished. There is something spoken of in even the Old Testament that was not accomplished at the cross.
Somehow many of us have been a little short sighted in our understanding of the great work of God. Does the fault fall on Jesus for misleading us at the cross? Was He a little presumptuous of His own work on behalf of mankind? After all it wasn’t all finished at the cross now was it not.
It is not Jesus who has mislead the congregation but we ourselves. We fail to understand that Jesus work on the cross was not the entire work of God. Just as we fail to understand the work in our lives is not finished until our race is done. Just as we fail to understand that we who run the race have a hope of salvation. Until we finish our race, His work in our lives is not finished.
Jesus did accomplish what He was supposed to do, but He did not accomplish all the work of God. He did come to become the savior of the whole world, and this He accomplished.
And we have seen and do testify that the Father sent the Son to be the Saviour of the world.
Through Christ the work needed to bring us the forgiveness of our sins has been accomplished. Not the full work of God.
Him hath God exalted with his right hand to be a Prince and a Saviour, for to give repentance to Israel, and forgiveness of sins.
If all the work of God is not finished, even though Jesus has accomplished what He was sent to do, what do you think is the still yet unfinished work of God? What is this mystery spoken of in Revelation?
