You might think that this is an allusion to God talking to the Israelites before He lays the ten commandments on them (See Exodus 20:2). “I am the LORD your God, who brought you out of the land of Egypt, out of the house of slavery.” Yeah, that sounds about right.
The quote is referenced on other occasions, as well. See Ex. 29:46, Leviticus 11:45, Deuteronomy 5:6, Judges 2:1 as examples.
It was referenced because Israel would need this reminder of the great works of God as they were in exile in other places, at other times.
But it is not the first time God “brought” someone “out of” somewhere. Genesis 15:7 notes: “He also said to him, “I am the Lord, who brought you out of Ur of the Chaldeans to give you this land to take possession of it.”
He took Abram, a Shemite idolator out of a distant land in the east, and brought him to Canaan. In this case, God took an uncircumcised gentile and began the process of creating a nation.
Genesis 14:13 notes: “One who had escaped came and reported this to Abram the Hebrew.” It is the first time we see this term use to describe a person. The term may mean “beyond” referencing the fact that Abram came from beyond the Euphrates River.
In essence, it means that Abram didn’t belong here. He was a sojourner, a foreigner.
God has done this for us, too. 1 Peter 2:9 says, “But you are a chosen people, a royal priesthood, a holy nation, a people belonging to God, that you may declare the praises of him who called you out of darkness into his wonderful light”. We were foreigners to God’s grace and mercy. We were sojourners in the darkness of our own sin. And, like Abram, we have a tendency to return to our own vomit, despite the promise given to us in Jesus Christ.
That promise is one you can hang your hat on. It is a promise that allows us to return from the darkness of sin, over and over again in repentance. It is a promise that does not depend on our emotions, perspective or achievement.
“Never will I leave you; never will I forsake you.” (Deut. 31:6, Heb. 13:5). These are the sure words of Christ, a sojourner to this world, a foreigner to sin, who “became sin for us”. He has taken all of it so that we can become His own people. In fact, we already are; in Jesus’ name.
