The Story
Moses, God's great leader, had died, and now Joshua stood in his place. God spoke to Joshua and told him the time had come: "Moses my servant is dead; now therefore arise, go over this Jordan" — the wide river Jordan — and take all the people into the promised land. God promised Joshua the same wonderful promise He had given Moses: "I will be with thee: I will not fail thee, nor forsake thee". And then God gave him the words of our memory verse: be strong, be brave, and do not be afraid, for the LORD thy God is with thee wherever thou goest.
Joshua told the people to get their food ready, for in three days they would cross the river. The camp moved down to the edge of Jordan. It was harvest time, when the river runs full and deep, right up over its banks — no one could swim that rushing water, and there were no bridges. But God had a plan.
Joshua sent the officers through the camp with God's orders: when the people saw the ark of the covenant — God's special golden box — carried by the priests, they were to follow it at a distance. Joshua told the people, "Sanctify yourselves: for to morrow the LORD will do wonders among you."
In the morning the priests lifted the ark onto their shoulders and walked ahead of all the people, straight toward the deep, rushing river. The moment the soles of their feet touched the edge of the water, God did the wonder! The water coming down from above stopped and stood up in a great heap, far away, and the water below flowed off toward the sea — and there, in the middle of Jordan, was dry ground. The priests carrying the ark "stood firm on dry ground in the midst of Jordan" while the whole nation walked across on dry land, every family, every child, every animal — nobody even got their feet wet.
When everyone was safely over, God told Joshua to choose twelve men, one from each tribe. Each man went back into the middle of the river and lifted a big stone onto his shoulder from the very place where the priests had stood. They carried the twelve stones to the camp at Gilgal and set them up in a pile. Joshua said that when children in years to come asked what the stones meant, their fathers were to tell them the story: "the LORD your God dried up the waters of Jordan from before you". Then the priests came up out of the river, and the moment their feet reached the dry bank, the waters of Jordan came rushing back and filled the river again, just as full as before. God had dried up the river for His people — exactly as He promised Joshua.
