Whom have I in heaven but you? And earth has nothing I desire besides you. My flesh and my heart may fail, but God is the strength of my heart and my portion forever. Psalm 73:25-26
Whether you are feeling physically fit today, or feeling worn and weary, take heart that God is the everlasting sustainer and strengthener of your soul. When our physical abilities or mental courage fail us, he upholds us. And more than that, his power is made perfect in weakness (2 Cor:12).
