Joshua was God’s designated man to take the Promised Land back, but he needed help to do it. But no one over the age of twenty was allowed into the land and before he could take them in, he had to circumcise them. Basically, Joshua’s generation failed to pass their spiritual legacy on to the next generation. While Joshua saw great miracles, Joshua’s children only heard about the miracles, and Joshua’s grandchildren worshiped Baal. This is a powerfully prophetic look at the spiritual relationship between the current generations working together to bring Jesus back again.
