John Calvin Commentary Micah 7:15

"As in the days of thy coming forth out of the land of Egypt will I show unto them marvellous things." — Micah 7:15 (ASV)

The Prophet here introduces God as the speaker, and God speaks in such a way as to answer the Prophet's prayer. God then promises that He will be wonderful in His works and provide such evidence of His power as He displayed when He brought His people up from the land of Egypt. We now see that there is more force in this passage than if the Prophet had initially said that God would become the deliverer of His people. For the Prophet interposed entreaty and prayer, and God now shows that He will be merciful to His people. At the same time, the faithful are reminded that they must be persistent in prayer if they desire to be preserved by God.

Now God says that He will show wonderful things, as when the people previously came out of Egypt. That redemption, we know, was an enduring monument of God’s power in the preservation of His Church, so that whenever He intends to give some hope of deliverances, He reminds the faithful of those miracles that they may feel assured that no obstacles will prevent them from remaining in a state of safety, provided God is pleased to help them, for His power is not diminished.

And this deserves to be noted, for although we all acknowledge the omnipotence of God, yet when we struggle with trials, we tremble as though all paths to our preservation were closed to God. Therefore, as soon as any impediment is thrown in our way, we think that there is no hope. Why is this? It is because we take no account of God’s power, which we nevertheless confess to be greater than that of the whole world.

This is the reason why God now refers to the miracles which He performed when the people came forth. They ought to have known that God always remains the same, and that His power remains as perfect as it was previously. Indeed, there is sufficient support in Him to encourage the hope of assistance.

We now perceive the Prophet's objective. He indeed changes the persons; for in the beginning He addresses the people, according to the days of your going forth, and then He adds, אראני, aranu, I will make him to see; but this change does not obscure the meaning.

For God only means that His power was sufficiently known previously to His people, and that there was a memorable proof of it in their redemption. Consequently, the people could not have doubted their safety without being ungrateful to God and without burying in oblivion that very memorable benefit which God once conferred on their fathers.
