Moses brought our people together in the desert, and the angel spoke to him on Mount Sinai. There he was given these life-giving words to pass on to us.
It troubled the LORD to see them in trouble, and his angel saved them. The LORD was truly merciful, so he rescued his people. He took them in his arms and carried them all those years.
This was the same Moses that the people rejected by saying, "Who made you our leader and judge?" God's angel had spoken to Moses from the bush. And God had even sent the angel to help Moses rescue the people and be their leader.
They are the descendants of Israel, and they are also God's chosen people. God showed them his glory. He made agreements with them and gave them his Law. The temple is theirs and so are the promises that God made to them.
What is the use of the Law? It was given later to show that we sin. But it was only supposed to last until the coming of that descendant who was given the promise. In fact, angels gave the Law to Moses, and he gave it to the people.
What God has said isn't only alive and active! It is sharper than any double-edged sword. His word can cut through our spirits and souls and through our joints and marrow, until it discovers the desires and thoughts of our hearts.
By now you should have been teachers, but once again you need to be taught the simplest things about what God has said. You need milk instead of solid food.
If you have the gift of speaking, preach God's message. If you have the gift of helping others, do it with the strength that God supplies. Everything should be done in a way that will bring honor to God because of Jesus Christ, who is glorious and powerful forever. Amen.
