Death

Adam was created natural (not spiritual), directly from the Earth. God told Adam he would certainly die, if he ate the fruit from the forbidden tree. This transgression would cut him off, and all humans born after him, from eternal life.

And the Lord God commanded the man, “You are free to eat from any tree in the garden; 17 but you must not eat from the tree of the knowledge of good and evil, for when you eat from it you will certainly die.” Gen. 2:16-17.

St. Paul tells us that flesh and blood (the natural) cannot inherit God’s Kingdom in its present state but it must be changed into imperishable spirit.

I declare to you, brothers and sisters, that flesh and blood cannot inherit the kingdom of God, nor does the perishable inherit the imperishable. 51 Listen, I tell you a mystery: We will not all sleep [die], but we will all be changed— 52 in a flash, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, the dead will be raised imperishable, and we [living believers] will be changed. 53 For the perishable must clothe itself with the imperishable, and the mortal with immortality. I Cor. 15:50-53.
