The beauty of God's strength is it is only activated when we surrender. The beauty of God's strength is it is made perfect in our weaknesses. One of our greatest weaknesses is trust in our own strength. However the true measure of strength in God's eyes is your ability to acknowledge your frailties. In a world that promotes individualism and being a self-made individual. God promotes trust in his Strength. He wants to be your strength!
If we truly understood the omnipotence of God we would delight in trusting in HIS strength. God wants to be your refuge and very present help in your time of trouble. So the moment you can't do God will do, but as long as you try to do God will let you do. Look at the beauty of a God who wants do for you what you can't do for yourself!
