1 Corinthians 1:18, "For the message of the cross is foolishness to those who are perishing, but to us who are saved it is the power of God."
Simply stated, knowing what Christ did for us on the cross, it is the power of God or in other words, it activates the power of God. The Greek word Paul used for power here is "dunamis." It is where we get our word dynamite from. It means miracle-working power! Certainly not a power that comes from the efforts of flesh and blood, but only from an infinite omnipotent mighty God!
By Jesus' death on the cross, He provided and accomplished everything we need to walk in victory in this life here on this earth. With His stripes and nail scarred hands, He paid for complete healing of our bodies, our minds and our spirits (Isaiah 53:4-5).
Did you know that Jesus received the judgment and punishment for all the sins we committed, past, present and future on the cross? It was all finished over 2,000 years ago, even before we were born - one sacrifice once and for all (Hebrews 10:10-14). He is not coming back to again be re-crucified for every new sin we commit. It is a gift and free! We just have to receive it. His gift is for us in the here and now because we won't need the victory of the cross when we get to Heaven for there is no sickness, disease, emotional trauma or pain in Heaven. We need it while living here on this earth.
According to the above scripture, when you understand what Christ did for you on the cross, you will begin to experience His dynamite miracle-working power! Amen!
