To defend the position of Moses

The role of Moses is more than a Liberator, a Saviour. Once the Israelites were brought out of Egypt, Moses faced the problem of keeping this mob of slaves alive. To stay alive, they needed solidarity. In other words, Moses had to build a nation out of these reluctant freedmen. His task was daunting and he had always been challenged by this rebellious crowd. He needed to give them a Law to live by. So, Moses the Liberator became Moses the Law-Giver.

This people belong to God. Naturally, the Law to help this people lead their life and survive among hostile peoples must come from God. Moses was the middle-man, shuttling between God and the Israelites. In order to succeed, Moses needed the support of God to confront more than 600000 rebellious Israelites. God played His role impressively.
These words the LORD spoke to all your assembly at the mountain out of the midst of the fire, the cloud, and the thick darkness, with a loud voice; and he added no more.
(Deuteronomy 5:22a).
God spoke out of the midst of the fire, the cloud and the thick darkness with a loud voice. Surely, such a show inspired awe and fear in the audience. They were afraid and this was the beginning of wisdom (Psalm 111:10, Proverbs 9:10).
Meanwhile, at the request of the people, Moses became the go-between. He went before the Lord to receive instructions and passed on God's words to the Israelites.
Go near, and hear all that the LORD our God will say; and speak to us all that the LORD our God will speak to you; and we will hear and do it (Deuteronomy 5:27).

After passing on the Ten Commandments to the Israelites in a spectacular manner, Moses' role as the Law-Giver was established. On the other hand, God did not need Moses to report to Him how the Israelites behaved. He could see and hear them all by Himself. He sent Moses back to assure the people.
and the LORD said to me, 'I have heard the words of this people, which they have spoken to you; they have rightly said all that they have spoken. 
Oh that they had such a mind as this always, to fear me and to keep all my commandments, that it might go well with them and with their children for ever! (Deuteronomy 5:28b-29)
God wished that the Israelites would hear and do His commandments forever so that they would live forever. That was and is the will of God, that we listen to Him and do His commands.
Moses had played his role and God His. It remained for the Israelites to play theirs. Unfortunately, the Israelites had failed.

Dear Lord, You always wish that we may share Your eternal life. You have done a lot and I do not see what else You have not done. I pray that I may listen to You and do Your will. I pray that my life can be a prayer of praises to You. Amen.
