And Moses summoned all Israel and said to them: “You have seen all that the Lord did before your eyes in the land of Egypt, to Pharaoh and to all his servants and to all his land, the great trials that your eyes saw, the signs, and those great wonders. But to this day the Lord has not given you a heart to understand or eyes to see or ears to hear. I have led you forty years in the wilderness. Your clothes have not worn out on you, and your sandals have not worn off your feet. You have not eaten bread, and you have not drunk wine or strong drink, that you may know that I am the Lord your God.
Deuteronomy 29:2‭-‬6 ESV

The Israelites had seen with their own eyes all that the Lord had done in Egypt, the trials and the signs and the wonders. They’d seen the ten plagues that God had sent on Egypt and they’d seen God open the Red Sea for them to escape.

Their eyes had seen it, but the Lord had not given them a heart to understand or eyes to see or ears to hear.

So, God led them through the wilderness, providing for them for 40 years, giving them food and water and preserving their clothing, so that they would know that He alone is the true Lord, their God.

God wants us to know Him. God wants us to know that He is the Lord and sometimes that means He has to lead us through the wilderness.

God wants us to see Him in the trials and in the wonders.

Do you know that He is the Lord? Do you trust Him today? If you don’t, will you start seeking Him today? He wants you to know Him.
