Moses was chosen by God to free the Hebrew slaves from Egypt. Once they were free God proceeded in four distinct phases to make them into the nation He promised, the Exodus, the Covenant Agreement, the Deacalogue and Code of Laws, and the instructions for the Tabernacle and Priesthood.
After all that God had done to him the Pharaoh of Egypt still would not let the Hebrew Slaves leave. To show the Pharaoh, his followers, and the Hebrews how truly powerful He was, God ordered the Hebrews to kill a lamb and put the blood on two side posts and the upper door on all of their homes. That night He would go into Egypt and kill all first born children of men and animals. He would pass over the homes with the blood of the lamb over the door so they would not bear the wrath that He was taking out on the people of Egypt. This was His token for His people. He expected them to honor the day of the Passover forever more. God was showing His love for His children along with His awesome power. This marked the day of Israeli’s birth and freedom from Egypt.
After the Israelites left Egypt and were at the Sea of Reeds, God once again hardened the Pharaoh’s heart so that he would come after the Israelites. The children of Israel were afraid when they saw the Egyptians coming after them. They had no place to go. Moses told them the Lord was there to save them. Through Moses, God split the sea and the children of Israel entered. The Egyptians followed them because God had hardened their hearts. Once God’s children were safe, God had Moses return the water and all of the Egyptians died. God had saved His chosen children, thus making them see how powerful He was so that they would fear Him and believe in Him and in Moses as His servant.
Once God’s children were settled into the wilderness, God told them that they must obey Him and keep his Covenant because they are His people. They must put Him above anything else on the Earth. He loved them and remained faithful to the promise He made Abraham. He expects them never to forget that they are His and to honor Him always.
After He freed the children of Israel from Egypt, God gave them the most important writing of all, the Decalogue, also known as The Ten Commandments. The Decalougue was written by God and was His most perfect code of laws for men to obey. Before the Decalogue man followed God, but had no clear rules to follow. Once the Decalogue was introduced, man knew exactly what God wanted of him and had definite rules to follow. The Decalogue is important for the morality of all mankind. Without it the children of Israel did not clearly know how to obey God. The Code of Laws, also known as the Book of the Covenant, is a continuation of the Decalogue. The children of Israel needed laws to teach them how to deal with other people, and obey God at the same time. If God’s children obeyed all of His laws He would protect them. He was preparing them to be a righteous, powerful, and loyal Nation duty bound only to Him.
Once the children of Israel had their laws established they needed a place where they could worship God. He told them to build a temple and He would dwell there and help them through troubled times, as long as they put all they had into building the Temple. They were to build it just as God told them to, this prepared them to be willing to give freely, not begrudgingly. God comforted and cared for them only asking them for their loyalty and obedience in return. The Temple needed those to govern it, so the priesthood was established. Those who entered the priesthood had to make sacrifices, wear special clothes, and worship in the Temple to show that they would not take God for granted. They were the leaders of the church who people could go to for guidance.
God promised Abraham a great Nation, there was a time when His children were held captive, but hearing their cries He delivered them from evil. Through the Exodus, Covenant Agreement, Decalogue and Code of Laws, and instructions for the Tabernacle and priesthood God taught them to honor Him and only Him. He taught them to obey the laws of the land that He set forth for them. He wanted them to be just like Him. He transformed them into a powerful and moral Nation that He would always love and protect just as He promised Abraham.
