At the end of the day, we all die. Therefore, it is not God’s desire to keep our body alive in this life. He is far more concerned with our spirit. That is what lives on eternally. Our bodies will perish but who we are continues forever. Our life on this earth is not the entirety of our existence. We are simply passing through. Our bodies get ill, as do our minds, but the essential part of us, the part made in the image of God, continues to eternal life with God.
