Why do we sing this song and praise the Lord and shake our right arm, left arm, right leg, left leg, etc?
It is because God came to Abraham and graciously made a covenant with him. Abraham was to be the Father of many nations. He would be patriarch over the line that would produce the seed of Eve who would one day crush the head of the serpent (Genesis 3:15).
The lesson we are studying this week is crucial for our understanding of biblical Christianity. Here we see God establishing a binding covenant that stands even to this day. Through Abraham, God would establish his people of promise, Israel. Now, through Christ, we are grafted into the true family of Abraham. Paul says so much in Galatians 3:29. “And if you are Christ’s, then you are Abraham’s offspring, heirs according to promise.”
The promises made by God to Abraham are now in play for the sons and daughters of Abraham. The sons and daughters of Abraham are those who are in Christ. It is a great blessing to be an heir according to promise.
So when we sing that favorite kids’ song, let’s do what it says.
“So let’s all praise the Lord!”
