O Adonai and ruler of the house of Israel,
Who appeared to Moses in the burning bush and gave him the Law on Sinai:
Come with an outstretched arm and redeem us.
When the Lord revealed Himself to Moses through the burning bush. Moses asked what God’s name was. The reason for this was that in Egyptian and Canaanite religions, if one knew the name of a god, it was thought that they could have control over that god. However the Lord is not like all the false gods of Egypt and Canaan and so God revealed Himself as Yahweh: “I will be who I will be” (or I am who I am). In revealing this name to Moses God made a strong statement as if to say “I cannot be controlled like all the false gods. Adonai is the Hebrew word for Lord. Quite early on, Israelites substituted Adonai for Yahweh so as not to possibly take the name of the Lord in vain. In fact, this is why most English translations translate Yahewh as LORD (in all caps). As Yahweh revealed Himself to Moses, He also gave Moses a promise: that He would free His people and that they would worship God on that mountain.
Sin takes hold of us and binds us in slavery. It is not uncommon for a Christian to have their “pet” sins… the ones we hate and yet find ourselves falling into on a regular basis. The more one is made aware of the enormity of their sinful state, the heavier those shackles of sin can be. Our Small Catechism echos the words of St. Peter (1 Peter 1:18-19), that Jesus has redeemed us, not with gold or silver, but with His precious blood.
For those who are crushed by the weight of the shackles of their sin, this prayer hits home. Come Lord Jesus, redeem us… free us. With our eyes fixed on the cross, we can be sure that our prayer has been heard and that we are free indeed.
