It's All About Him: Hebrews -- Lesson 47
The Writer moves from Moses to the first battle for the land of Canaan:
By faith the walls of Jericho fell down after they had been encircled for seven days. (Hebrews 11:30, NASB 95)
The normal way to lay siege to a city is to encamp around it and wait for dwindling supplies within to take their toll. If need be, siege engines can be built to pass the time. The Lord commanded Joshua to have his army march around the city seven times over the course of seven days. In front they marched the Ark and at the end of seven days it was the priests who sounded the trumpets. All this was to show the children of Israel that their victory came from the Lord and not from themselves. It also announced to the inhabitants of the land, that the new owners had arrived.
Through faith, God can ask us to take risks and do things out of the ordinary. He can ask us to do things which will make us look silly--unless He does His part--and we never know beforehand that He will do this--that is where faith comes in. Faith obeys and accepts the consequences.
Test everything. Cling to what is good.
