My flesh and my heart may fail, but God is the strength of my heart and my portion forever (Psalm 73:26).
God does not promise a life without physical problems. No matter how “in shape” we are, the body eventually dies. No one lives forever on this earth. Decay is a natural occurrence brought on by man’s original disobedience. Our wit, our senses, our desires, our dreams diminish as we age. The good news is that God will keep our energies afloat to fulfill His good purpose. Do Christians suffer from dementia? Yes. Do Christians suffer from paralysis and debilitating disease? Yes. But, God is able to transcend these limitations. The Bible teems with stories of heroes who overcame seemingly impossible odds to further the Kingdom. David lived like a hunted animal in fear of Saul. Joseph became a leader even in prison. A slave girl led a Roman official to Jesus. God is not limited by our limitations. Rather He uses them so that none can boast of their own strength.
