Sin.. sinful nature... leads to physical death

1. Adam's sin caused our bodies to decay and die which then translate illnesses will cause us to die. Romans 5:12 [ Death Through Adam, Life Through Christ ] Therefore, just as sin entered the world through one man, and death through sin, and in this way death came to all men, because all sinned— 2. Now, if you are talking specific illnesses such as genetic, then its part of family's sin passed on from generation to generation. (Sciencific facts) 3. There are some who were born ill (disabled) no fault of the child. God created my inmost being and knitted me together in my mother's womb. As you do not know the path of the wind, or how the body is formed in a mother's womb, so you cannot understand the work of God, the Maker of all things. This is what the LORD says— "He who made you, Who formed you in the womb, and Who will help you and that before I formed you in the womb I knew you, before you were born I set you apart. In Him we were also chosen, having been predestined according to the plan of Him who works out everything in conformity with the purpose of His will. The LORD said to Moses, "Who gave man his mouth? Who makes him deaf or mute? Who gives him sight or makes him blind? Is it not I, the LORD ?" I was born this way so that the work of God might be displayed in my life and I know that in all things God works for the good of those who love Him, who have been called according to His purpose. With man this is impossible, but not with God; all things are possible with God. 4. Of course, people sow their sinful nature will reap. Galatians 6:8 The one who sows to please his sinful nature, from that nature will reap destruction; the one who sows to please the Spirit, from the Spirit will reap eternal life. We can go on and on regarding our bodies carrying our sinful nature caused by Adam. 1 Corinthians 15:22 For as in Adam all die, so in Christ all will be made alive.
