2 Kings 6:1-7 (NIV)
The company of the prophets said to Elisha, “Look, the place where we meet with you is too small for us. Let us go to the Jordan, where each of us can get a pole; and let us build a place there for us to meet.” And he said, “Go.” Then one of them said, “Won’t you please come with your servants?” “I will,” Elisha replied. And he went with them. They went to the Jordan and began to cut down trees. As one of them was cutting down a tree, the iron axhead fell into the water. “Oh no, my lord!” he cried out. “It was borrowed!” The man of God asked, “Where did it fall?” When he showed him the place, Elisha cut a stick and threw it there, and made the iron float. “Lift it out,” he said. Then the man reached out his hand and took it.

1 Timothy 4:7-8 (TLB)
Don’t waste time arguing over foolish ideas and silly myths and legends. Spend your time and energy in the exercise of keeping spiritually fit. Bodily exercise is all right, but spiritual exercise is much more important and is a tonic for all you do. So exercise yourself spiritually, and practice being a better Christian because that will help you not only now in this life, but in the next life too.
