The children of Israel were miserable in Egyptian bondage – the slavery was killing them. I’m not sure they knew who they were crying out to in Exodus 2:23-25 but I am sure of the one who heard them. It was the Great I AM, the creator God of this universe, and He was going to deliver them. The Great I AM is the greatest promise keeper ever. He remembered the covenant He made with Abraham, Isaac, and Jacob. So God raised up Moses to lead the children of Israel out of their bondage, cross the Red Sea into the wilderness, and eventually bring them into the promised land. He is truly the Great I AM.
We are like the Israelites: we were in misery – our sins kept us in bondage/slavery, and we were (spiritually) dead in our sins (Ephesians 2:1). We cried out to God and He heard us. He sent Jesus, His only begotten Son, into the world to save/deliver us from our bondage/slavery of sin. The Great I AM is the greatest promise keeper ever, and He fulfilled His promise through Abraham in that “all the families of the earth would be blessed in him” – all the way from Genesis 12:3 to Galatians 3:6-9.
When we put our faith in Jesus we are baptized into Christ, and like the Israelites, we are brought through water to safety/salvation by the grace of God in the blood of the Lamb (I Peter 3:20-21). And, just like Israel needed to be faithful to God, we need to continue to live by faith in the wilderness (life on earth) until we finally enter the promised land of heaven.
What is extra special/awesome is that Jesus Christ is the Great I AM as we read John’s gospel (John 8:48-59). Jesus is the eternal Son of God who came to earth to carry out the promise of God. We have the honor of fellowship with the Great I AM all the way from here to heaven as His Holy Spirit lives in us as a down payment for the future inheritance as THE children of God.
Read Galatians 3:15-22 and listen to The Great I Am by Phillips, Craig & Dean.
Galatians 3:15-22
Why the Law then? It was added on account of the violations, having been ordered through angels at the hand of a mediator, until the Seed would come to whom the promise had been made. Now a mediator is not for one party only; but God is only one. Is the Law then contrary to the promises of God? Far from it! For if a law had been given that was able to impart life, then righteousness would indeed have been based on law. But the Scripture has confined everyone under sin, so that the promise by faith in Jesus Christ might be given to those who believe.
