While the work of Christ becoming a curse is certainly sufficient for all mankind, it is by no mean effective for all mankind. Not everyone who is born into the human race experiences God’s blessing. In fact, because we are all born with a nature so sinful and corrupt, we are all under the wrath and condemnation of God until we come to faith in Christ. In 2 Corinthians 4:4-6 Paul writes:
“The god of this world has blinded the minds of the unbelievers, to keep them from seeing the light of the gospel of the glory of Christ, who is the image of God. For what we proclaim is not ourselves, but Jesus Christ as Lord, with ourselves as your servants for Jesus’ sake. For God, who said, “Let light shine out of darkness,” has shone in our hearts to give the light of the knowledge of the glory of God in the face of Jesus Christ.”
When we first had faith in Christ is when the Holy Spirit first opened our eyes and we saw the glory of God in the face of Christ and said, “YES! I want you, Jesus!” Christ carried on him the full weight of our sin. When God looked on Christ as he hung on the cross he saw our sin, and in all righteousness, God condemned our sin in Christ. As Paul says in Romans 8:3-4:
“For God has done what the law, weakened by the flesh, could not do. By sending his own Son in the likeness of sinful flesh and for sin, he condemned sin in the flesh, in order that the righteous requirement of the law might be fulfilled in us, who walk not according to the flesh but according to the Spirit.”
Christ became a curse for us by taking on our sin. But this is not all that happened. Christ did not only take our sin, at the cross, we also take Christ’s righteousness. As Paul says in 2 Corinthians 5:21:
“For our sake he made him to be sin who knew no sin, so that in him we might become the righteousness of God.”
At the cross, two transactions took place. Christ took on our sin and we took on Christ’s righteousness. Because of this, Christ has already given us everything we need to be fully accepted by God. In Christ is the only place God may look upon sinful men with benevolent kindness. In Christ is the only place that God may make his face to shine upon us and we, in turn, experience the benefits of those blessings.
