He predestined us to adoption as sons through Jesus Christ to Himself, according to the kind intention of His will,…
We are not adopted into the family of God we are born again by His Spirit into God’s family. The term “adoption as sons” refers to us being placed in a position of sonship, which we did not have before being born again. The children of Israel once taken captive in Egypt were slaves to Pharaoh and lived their lives under his control, but God sent Moses and delivered them.
Moses was a type of Jesus, and Egypt a type of the world. Like the children of Israel we have been delivered through Jesus Christ from Egypt (the world), no longer slaves to the world and it’s ways. But the first generation of Israel did not enter the promise land, the new way of living God had for them except for Joshua and Caleb. The problem was God had gotten them out of Egypt, but He could not get Egypt out of them. Their thinking had not changed and they did not see themselves as sons and daughters of God. This hindered their faith in God and His ability.
Scripture tells us they limited God. Why? Because they did not renew their minds to who they now were, no longer slaves but sons and daughters of the Most High God. So it is with many born again today. They have been taken out of Egypt, but if they will not renew their minds to who they have become in Christ they have not gotten Egypt out of them. Romans 12:2 tells us not to be conformed to this world, but be transformed by the renewing of your mind. Doing so will help every believer to rise up into the promise of the new life God has provided for them.
