The entire human race, however, is against His law and is breaking it. Therefore, the sinning race of mankind is under a curse, the curse of the law. This is the reason there are so many calamities, tragedies, and sicknesses, all of which are an indication that mankind is under the curse. But God is full of mercy, and He gives people a chance to repent. When we repented and were forgiven by God, we were released from the curse of the law.
As descendants of Adam, all sinners are under the curse. In Romans 5 we see that Adam brought us all under the curse. However, the curse was not made official until the law was given. Now the law declares that all the fallen descendants of Adam are under the curse. Whereas the law condemns us and makes the curse official, Christ through His crucifixion has redeemed us out of the curse of the law. “Christ has redeemed us out of the curse of the law, having become a curse on our behalf; because it is written, Cursed is every one hanging on a tree” (Gal. 3:13). Therefore, the curse that came in through Adam’s fall has been dealt with by Christ’s redemption.
The origin of the curse is man's sin (Gen. 3:17). The curse is carried out through the law, for the law administers the curse. Therefore, the curse is related to the law of God; it is the demand of the righteous God upon sinners.
The sign of the curse is thorns. After Adam sinned, the earth brought forth thorns because of the curse. So thorns are the sign of being cursed. The outstanding feature of thorns is that they prick, causing pain.
When Christ bore our sins, He also took our curse. Because Christ was cursed in our place, the demand of the law was fulfilled, and He could redeem us from the curse of the law. Now, as believers, we are freed from the curse of the law.
