The Israelites were in bitter slavery in Egypt. Here is what God told Moses. Exodus 6:5-7 “And I have also heard the groaning of the children of Israel whom the Egyptians keep in bondage, and I have remembered My covenant. Therefore say to the children of Israel: ‘I am the Lord; I will bring you out from under the burdens of the Egyptians, I will rescue you from their bondage, and I will redeem you with an outstretched arm and with great judgments. I will take you as My people, and I will be your God. Then you shall know that I am the Lord your God who brings you out from under the burdens of the Egyptians.’” God’s plan was to do mighty works so that the Israelites would know that the Lord was their God who saved them. Exodus 10:1-2 “Now the Lord said to Moses, ‘Go in to Pharaoh; for I have hardened his heart and the hearts of his servants, that I may show these signs of Mine before him, and that you may tell in the hearing of your son and your son’s son the mighty things I have done in Egypt, and My signs which I have done among them, that you may know that I am the Lord.’” As a result of the Egyptian plagues, the Israelites for following generations would know that He was the Lord.
Pharaoh finally told the Israelites to leave Egypt. But when they came to the Red Sea, Pharaoh changed his mind and pursued the Israelites. Exodus 14:15-18 “And the Lord said to Moses, ‘Why do you cry to Me? Tell the children of Israel to go forward. But lift up your rod, and stretch out your hand over the sea and divide it. And the children of Israel shall go on dry ground through the midst of the sea. And I indeed will harden the hearts of the Egyptians, and they shall follow them. So I will gain honor over Pharaoh and over all his army, his chariots, and his horsemen. Then the Egyptians shall know that I am the Lord, when I have gained honor for Myself over Pharaoh, his chariots, and his horsemen.’” When God created a pathway through the sea and destroyed Pharaoh’s army, He did so that the Egyptians (and other peoples) would know that He was the Lord. Years later, when the Israelites started to enter the promise land, this is what Rahab told the spies that she hid. Joshua 2:9-12 “And said to the men: ‘I know that the Lord has given you the land, that the terror of you has fallen on us, and that all the inhabitants of the land are fainthearted because of you. For we have heard how the Lord dried up the water of the Red Sea for you when you came out of Egypt, and what you did to the two kings of the Amorites who were on the other side of the Jordan, Sihon and Og, whom you utterly destroyed. And as soon as we heard these things, our hearts melted; neither did there remain any more courage in anyone because of you, for the Lord your God, He is God in heaven above and on earth beneath.’” The peoples of the land knew that the Lord was God.
When the Israelites came to the wilderness, they had no bread and no meat. Exodus 16:11-12 “And the Lord spoke to Moses, saying, ‘I have heard the complaints of the children of Israel. Speak to them, saying, ‘At twilight you shall eat meat, and in the morning you shall be filled with bread. And you shall know that I am the Lord your God.’” God gave them quail and manna to eat in the middle of the desert so that they would know that He was the Lord their God.
Near the end of his life, Moses spoke to the Israelites. Deuteronomy 29:2-6 “Now Moses called 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 which your eyes have seen, the signs, and those great wonders. Yet the Lord has not given you a heart to perceive and eyes to see and ears to hear, to this very day. And I have led you forty years in the wilderness. Your clothes have not worn out on you, and your sandals have not worn out on your feet. You have not eaten bread, nor have you drunk wine or similar drink, that you may know that I am the Lord your God.” God led and protected them in the wilderness for forty years so that they would know that He was the Lord their God.
David went to fight the giant Goliath. 1 Samuel 17:45-47 “Then David said to the Philistine, ‘You come to me with a sword, with a spear, and with a javelin. But I come to you in the name of the Lord of hosts, the God of the armies of Israel, whom you have defied. This day the Lord will deliver you into my hand, and I will strike you and take your head from you. And this day I will give the carcasses of the camp of the Philistines to the birds of the air and the wild beasts of the earth, that all the earth may know that there is a God in Israel. Then all this assembly shall know that the Lord does not save with sword and spear; for the battle is the Lord’s, and He will give you into our hands.’” David conquered the giant through the power of God so that all the earth would know that there was a God in Israel and that the assembly would know that the battle is the Lord’s and He will give it into the hands of His people.
Jesus did many miracles to include healing the sick, casting out demons, and raising the dead. He told the people in John 10:37-38 “If I do not do the works of My Father, do not believe Me; but if I do, though you do not believe Me, believe the works, that you may know and believe that the Father is in Me, and I in Him.” The mighty works that Jesus did were done so that we may know and believe that the Father was in Him, and He in the Father.
Do you know that the Lord is God? Do you know that the battle is the Lord’s and He will give it into your hands? Even today, God works in your life so that you may know that the Lord is God. He saves you. He answers your prayer. He gives you strength. He blesses you. He gives you wisdom. You have many reasons to know that the Lord is God.
There is coming a day when He will judge the world. Paul spoke to the Athenians in Acts 17:30-31 “Truly, these times of ignorance God overlooked, but now commands all men everywhere to repent, because He has appointed a day on which He will judge the world in righteousness by the Man whom He has ordained. He has given assurance of this to all by raising Him from the dead.” God raised Jesus from the dead so that we may know and be assured that there is a coming judgement. I encourage you to know that the Lord is your God and that you be ready for the coming judgement.
