In God’s original plan, He created the human body to be impregnable. Man was made to live long and free of sickness, disease or anything that hurts. However, Adam’s disobedience introduced death into the fabric of everything, his own body included. “Death” here doesn’t only imply the cessation of life; it also means “to fail,” “to be damaged” and to “fade away.”
Thus, Adam’s disobedience introduced failure and damage to the world. Man, who was created in God’s image, could now fall sick. His heart, liver, kidney etc., could now fail. When Jesus came, however, He defeated the devil and his cohorts and seized from him the keys of hell and death. The Bible says in 1 John 3:8, “…For this purpose the Son of God was manifested, that He might destroy the works of the devil.” After He destroyed the hold of sin and death over your life, He then declared, “...Sin shall not have dominion over you, for you are not under law but under grace” (Romans 6:14)! Therefore, sin and all its negative effects, including sickness, failure, poverty, and death, have no dominion or power over you, for you are under grace.
The Lord Jesus has given you the victory over sin, sickness and death. The reason some Christians are still living in bondage to these things is their lack of knowledge (Hosea 4:6). Refuse to be in bondage to sickness, disease or the devil. Change that negative situation by the power of the Holy Ghost in you.
Confession
My body is the temple of the Holy Spirit. Therefore, I live above sickness, disease, infirmity and death. I have the life of God in me; my life is for the glory God. I’m a victor in Christ Jesus; no weapon fashioned against me shall prosper.
