Time has passed. If you read the previous passage in chapter 15 with a careful eye, you observe that it took them only three days to find the water they now enjoyed. But now it’s been a month and a half—more than forty days! I call that the test of time.

After God drowned Pharaoh’s entire army in the sea, for the first time in history Israel found herself living in the Egyptian desert, out in the open, completely on her own. The Hebrews had begun their journey to the land of Canaan. God had proven Himself faithful; the nation had walked through the sea on dry land. How awestruck they must have been!

Had we been in charge of the Red Sea project, we would have handled it differently. Our group of engineers would have pushed back that water a week in advance. We would have installed great, massive fans to dry out the land. We would have erected huge neon signs.

The instruction Moses gave was to be passed along from generation to generation. After he finished with these specific instructions, Scripture says, “And the people bowed low and worshiped. Then the sons of Israel went and did so; just as the LORD had commanded Moses and Aaron, so they did” (vv. 27–28).

The main point, the central ingredient of Exodus 11 and 12, is obedience. God spoke, some people heard and did what God said. As a result, God used them in His plan at that time in history.

I’m convinced this dreadful display of judgment in Egypt, this battle between a righteous, holy God and the stubborn heart of Pharaoh, has at least two major truths to teach us. First, when God judges, He does a thorough job of it. Second, it is a fearful thing to fall into the hands of the living God.

Right after God told Moses what He would do, He said to him, “You must believe it. I command you to do this thing.” “Now the LORD spoke to Moses and Aaron about the Israelites and Pharaoh king of Egypt, and he commanded them to bring the Israelites out of Egypt” (v. 13 NIV).

So many times you and I miss the opportunity to watch the Lord work in mighty and miraculous ways. Why? Because instead of “standing still” and watching Him pull off our deliverance, we seek out the carnal alternative. We look for the back-door escape, a fleshly shortcut.

Moses felt as low as a slug’s belly. Way down there. He still hadn’t rid himself of the idea that he was supposed to be the deliverer, and that he was somehow failing. How many times had God explained it to him? Yet, like many of us, he had trouble keeping a grip on the Lord’s assurances.
