Then the Lord said to Moses, “Rise up early in the morning and present yourself to Pharaoh, as he goes out to the water, and say to him, ‘Thus says the Lord, “Let my people go, that they may serve me. Or else, if you will not let my people go, behold, I will send swarms of flies on you and your servants and your people, and into your houses. And the houses of the Egyptians shall be filled with swarms of flies, and also the ground on which they stand. But on that day I will set apart the land of Goshen, where my people dwell, so that no swarms of flies shall be there, that you may know that I am the Lord in the midst of the earth. Thus I will put a division between my people and your people. Tomorrow this sign shall happen.”’” And the Lord did so. There came great swarms of flies into the house of Pharaoh and into his servants’ houses. Throughout all the land of Egypt the land was ruined by the swarms of flies. Exodus 8:20-24
It is not until the plague of flies that God see it’s His people apart from suffering with the Egyptians. They endured the waters turning to blood, the frogs, and the gnats, but not the flies.
God does not spare His people all of His judgment. This is important to remember as you consider whether or not the church goes through the Great Tribulation.
