Ex. 37:1-9 its all about God.

It's a wood. The trees on a hill are just stayed there like invalid. But God selected a bush to come down and talk to his servant Moses. There came Moses. The staff in Moses' hand thought, "this is a living wood. That is why God is using it". Then it heard that God was saying to Moses to throw down your staff. Moses did. The staff turned into serpent. God said to Moses again, "take it". The staff turned into normal. The staff is very happy. Moses lifted it in Egypt here came plagues. He lifted and they ceased. "Why are you praying Moses? Stretch your staff and divide the sea." God said to Moses. Moses obeyed and the sea divided. The staff understood that it's not about living or dead. It's all about God. He choses and it works.

One day God called Moses and told him to make an Ark with acasia wood. Now it's a wood again. 

After a long time a priest who is carrying the ark thought that the Jordan will give way to them like Red Sea gave way to them. He thought that Joshua will use the same principle of stretching the wood. So he hold the wood tight that is on his shoulders. He stood in the front row. When they reached Jordan, Joshua told them to touch the river with your feet. "Did I hear right?" the priest asked himself. Yes he heard right. He touched the river and it was stopped. The priests stayed there until the whole nation crossed the river. This priest wondered, he asked his friend who is carrying along with him "hey it seems our feet has some power". His friend is quiet. Joshua called 12 people. " bring 12 stones from the river and pile them here." Some one asked Joshua, " why sir?" Joshua replied, "the same question will be asked by your sons. Then tell them that how the Jordan was stopped"

They went to bring the stones. Joshua said "bring the stones from the place where the priests' feet are." The young priest thought "certainly something is there in our feet". When these priests carrying the ark came to the bank, the river turned to the previous state. "Yes, there is something in our feet" the priest told to himself again. Next day morning he went to the river alone. The river is flowing well. He looked around. He slowly touched the water with his feet. Nothing happened. He pushed a bit. Nothing seems to be happening. He pushed his feet into the water a little hard. Now he slipped and about to fall down. But someone hold his hand. It was Joshua. Joshua looked at him and said, "there is nothing in your feet. It was presence of God that makes the difference. The power of the presence of God is there in the ark. It can flow through your body. It's not living wood or dead staff. It's not the man or feet. It's all about God"
