Then the Lord asked him, " What is that in your hand?" "A shepherds staff" Moses replied. "Throw it down on the ground," the Lord told him. So Moses threw down the staff, and it turned into a snake! Moses jumped back. Then the Lord told him, "Reach out and grab its tail." So Moses reached out and grabbed it, and it turned back into a shepherd's staff in his hand. - Exodus 4:2-4
Pick up your staff and raise your hand over the sea. Divide the water so the Israelites can walk through the middle of the sea on dry ground. - Exodus 14:16 Seven priests will walk ahead of the Ark, each carrying a ram's horn. On the seventh day you are to march around the town seven times, with the priests blowing the horns. When you hear the priests give one long blast on the ram's horns, have all the people shout as lord as they can. Then the walls of the town will collapse, and the people can charge straight into the town. - Joshua 6:4-5 Then he (Samson) found a jawbone of a recently killed donkey. He picked it up and killed 1,000 Philistines with it. - Judges 15:15
He (David) picked up five smooth stones from a stream and put them into his shepherd's bag. Then, armed only with his shepherd's staff and a sling, he started across the valley to fight the Philistine (Goliath). - 1 Samuel 17:40
Gideon used a wool fleece to confirm God's will. (see Judges 6:36-40) Elisha used oil to show God's power to provide. (see 2 Kings 4:1-7) Jesus used five loaves of bread and two fish to feed a crowd of more than five thousand. (see Mark 6:30-44) There are many other examples.
God often uses simple, ordinary objects to accomplish his tasks in the world. What do you have that God can use?
