Luke 24:21 ‘But we trusted that it had been he which should have redeemed Israel: and beside all this, to day is the third day since these things were done.’
When the right time came, God sent forth His Son from Heaven in His pre-existent state, into the world. He was born of a woman (virgin birth) and was made subject to the requirements of the law. Jesus was sent at a specific time. The entrance of Jesus into the physical realm was not a random thing occurring at a haphazard time. There were developments that had to take place before Christ could come to earth and redeem man. The Father sent His Son to the earth at the earliest possible time. Anytime prior to the time Jesus was born of the virgin Mary, would have been premature.
His purpose for coming into the world was twofold. First, He came to ‘redeem them that were under the law.’ He did this by perfectly keeping the law, fulfilling it, and paying its curse (Mt. 5:17; Gal. 3:13). Thus, Christ delivered us from the entire system of the law. The Greek word for redeem means ‘to buy OUT OF the slave market.’
Secondly, Christ gave us the status of sonship with all its privileges. Not only were we redeemed from the bondage of the law, but we were redeemed unto sonship. Many people stop short, only realizing what they were delivered from, not what they inherit. Sure, we need to rejoice that we are redeemed, but we also need to move on, and realize the full benefits of our inheritance.
God created us for Himself but we sold ourselves into slavery to the devil. God bought us back through the precious blood of Jesus Christ. No amount of effort, human works, or man’s own righteousness could bring the divine favor that we needed. It was the actual life of God (Lev. 17:11) that purchased our redemption.
