The blessing of God supersedes the curse but doesn’t do away with the curse.
The blessing was given to Adam on the day he was created. On the day Adam died spiritually, when he ate from the forbidden tree, the curse was introduced into the earth.
Where did the curse come from? It was the curse that was on Satan after he rebelled against God. That was the precedent. The curse on Satan became the curse Adam inherited when Adam obeyed Satan: “Do you not know that to whom you present yourselves slaves to obey, you are that one’s slaves whom you obey, whether of sin leading to death, or of obedience leading to righteousness?” (Romans 6:16).
Fortunately, the curse isn’t such that it destroys everything immediately. Though it did immediately separate man from God, and the rest of creation began a dismal decent into destruction. That destruction of total annihilation was interrupted with God causing the flood.
The flood was like a reboot. Only after the reboot the curse was still in the earth. Why? Because humans, God’s shepherds of the earth, still reigned by the original authority granted to them from God (Genesis 1:28). Only now the human heart was by nature enmity against God.
After the Noah’s flood, we see the blessing of God re-administered: “So God blessed Noah and his sons, and said to them: ‘Be fruitful and multiply, and fill the earth. And the fear of you and the dread of you shall be on every beast of the earth, on every bird of the air, on all that move on the earth, and on all the fish of the sea. They are given into your hand. Every moving thing that lives shall be food for you. I have given you all things, even as the green herbs’” (Genesis 9:1-3).
At this point the blessing is back in the earth. Yet, the curse is in the earth also. The curse isn’t eradicated until the new heaven and the new earth is created: “And there shall be no more curse, but the throne of God and of the Lamb shall be in it, and His servants shall serve Him” (Revelation 22:3).
We live in an earth that is in constant threat of extinction because of the curse. The curse is the same doom that Satan lives under. Whatever he does dies. There is no life in the Devil — only the curse of death.
At the same time, we have access to the blessing of life in Christ Jesus: “For the law of the Spirit of life in Christ Jesus has made me free from the law of sin and death” (Romans 8:2).
The big question is how to get the blessing active in our life? The answer is, “The same as all those before us.” It comes through obedience, faith in the word of God, prayer, living a holy lifestyle, and confessing our sins when we sin.
The struggle is always with us — blessing or cursing — as individuals and as nations and people groups. Everyday we make choices. If we consistently choose those things that allow the curse into our lives and nation, the curse will begin to dominate. If we consistently choose what allows the blessing to dominate, the blessing will supersede the curse.
Think of it this way. The blessing is like an umbrella. As long as we stay under the umbrella, we’re covered from the rain. But if we get out from under the umbrella, the rain is already out there and we’re going to get wet.
The same is with the blessing. As long as stay under the blessing, we will enjoy it’s benefits. But if we get out from under the blessing, the reign of the curse is out there, and we’ll come under it’s domain.
