There was the wilderness on one side of the Jordan River and Canaan on the other. The Israelites had no other way to get to their promised land but to cross the river. 

But how were they supposed to get from one side to the other?

Through the help of the priests. They were going to stand in the middle of the river, holding the ark of the covenant, causing the waters to recede, making the way easier for the Israelites to cross. 

Essentially the priests were going to stand in the gap. 

Could you do the same for someone? Maybe it looks like praying for them? Helping them through a tough time? Encouraging them as they pass by?

Let’s be like the priests were. Stand in the gap for your fellow brothers and sisters in Christ.
