Do you know that it has never been the will of God for man to be sick or for man to die? Yes, it has never been part of God’s plan for man to sick or die.

Sickness and death we see today are some of the fruits, among others, inherited from the disobedience of Adam and Eve in the Garden of Eden (Romans 5:19). When Adam and Eve ate the forbidden fruit, they disobeyed God’s command that instructed them not to eat from the tree of the knowledge of good and evil and it was after which, sin and sickness and death came into the world (Genesis 2:17).

Man was never created to be sick or to die. When God created man, He placed man in the Garden of Eden and gave instruction to man not to eat from the forbidden fruit and that the day that they do, they will surely die (Genesis 2:17). That is the origin of the whole problem of the world and that was how sickness and death came into the world.

Adam ate from the tree, and though he did not die immediately, he died eventually and the death transferred to all his descendants.

Some sickness is caused by sin, but not all sickness is a result of sin. If all sickness is a result of sin, then all should be sick by now because all have sinned and fallen short of the glory of God (Romans 3:23).

Some of the sickness caused by sin are sickness that result from sinful activities like fornication that can result to sickness like HIV and aids (Ephesians 5:3); sickness caused by moral misconduct like smoking that can cause harm to the lungs, liver and other body systems. To overcome such sin, we need to forsake all unrighteousness and cleave to God that we might overcome all lust of the flesh and have total self control against self will (Romans 6:13; Galatians 5:16).

Some sickness is as a result of the affliction of the devil (Acts 10:38). The devil can afflict someone with a strange ailment to tempt him. He is given every room and opportunity to afflict us when we are active in sin. A man living a godly life cannot easily be afflicted by the devil because he is covered by the blood of Jesus and invincibly putting on the armor of God by which he is able to stand against all the wiles and arrows of the devil including sickness (Ephesians 6:11). Sickness afflicted by the devil can cured by prayers and faith healing.

God who can just put an end to the sickness in this present world, took a bold step in the right direction by sending forth His Son Jesus to die for us on the cross. Jesus Christ bore our sickness and infirmities on the cross (Matthew 8:17) which was inherited from the Adam’s era and that by His stripes we are healed (1 Peter 2:24; Isaiah 53:5).

Now through Jesus, we don’t only have hope for eternal life, but also, by the name of Jesus every sickness of any kind can be prayed upon and healed.

Mark 16:17-18 KJV
And these signs shall follow them that believe; In my name shall they cast out devils; they shall speak with new tongues; [18] They shall take up serpents; and if they drink any deadly thing, it shall not hurt them; they shall lay hands on the sick, and they shall recover.

Jesus has the power to heal and to forgive. Just turn from your wicked and sinful ways, and he will heal you of that sickness that has plagued your life for years ( 2 Chronicles 7:14; Exodus 15:26).
