Having considered the great and eternal plan of the Father, purposed before the foundation of the world for us – that we should be holy and without blame before Him, adopted and accepted in the Beloved – we now begin to consider how God’s eternal purpose is carried out through the person of the Son. Having had the grand plan laid out before our eyes, and seeing what is our highly favored position in Christ, verse 7, in a sense, brings us back to the reality that we are yet on earth, still human, still mortal, and still sinful. In order for us to arrive to our predestined position, something must be done with the problem of our sins which separate us from God. So God in His eternal wisdom and foreknowledge designed a way whereby men could and would be reconciled to Him. That way is Christ – in Him we have redemption. What Christ did on the cross at Calvary accomplished such redemption, as 2 Corinthians 5:19 tells us that God was, in Christ, reconciling the world unto himself. The work of Christ is the means that God uses to accomplish all that He had predestined to do in and through His people.
Redemption is required because mankind is sold into the slavery of sin. The whole world lies guilty before God in bondage to sin and under the yoke of Satan. On the cross, Christ accomplished the work that He said He would accomplish, by giving His life as a ransom for many, and thus purchasing us out of slavery. Today, if you are in Christ, you have been bought with a price, and that price was His own blood.
