Every time I read this story I ask myself why God would include a story about a floating ax head in the Bible. What great spiritual lesson can we glean from this expression of the power of God?
The power of God in your life as a follower of Jesus Christ is not just for the "big, important" things! God is certainly willing that His power be seen even in the small things in your life. I believe there is nothing too small to pray about. If something concerns you it is not inappropriate in the least to bring the matter to God in prayer!
The best way to be ready to trust God in the big things of life, is to trust Him every day in the little things. If you talk to God about the "little" stuff of life, then it will be a natural response to call on Him when the serious problems arrive!
"Lord Jesus, help me today to invite You into even the small problems that confront me this day. When I lose my ax head in the water today, send Your power to make it float! And may You be praised forever. Amen."
