God says He is going to do all this, which has a direct connection to why we eat unleavened bread. "I, I, I, I"—all uttered by God about what He will do. But the Israelites did not agree because the persecution that they had received just prior to this had put fear into them. So what does God have to do?
He could have thrown up His hands, but He said He would do these things. He had promised Abraham, Isaac, and Jacob to bring Israel into the Promised Land. Since God does not go back on His word, He decided to do it anyway, even though they do not agree. So God, in His mercy, began to work in a way to bring them into agreement with what He wanted to do. He did not give up, even though they were resisting Him stoutly at this time.
God had set His mind. Do we think God has made His mind up to save us? We had better believe He has! Nobody can resist Him! He will save us! But He will not save us until we come to the place where we really know that we did not do it. As hard as we might think it is, the part that we have to do—so tiny in comparison to what God does—He gave us the power to do! That is what Pentecost is about.
We have to come to understand that God is our Savior. All we have to do is cooperate! When we cooperate with His will, it works! His way of life works, and what He is creating in us will be created. As we see here, Israel dragged its heels, just as we do from time to time, resisting Him.
