Each gate in Jerusalem had a specific function and use. The natural gates of the city of Jerusalem still have symbolic or metaphoric meaning in our lives today. Life has done it's best to knock us down, but having the right people in our lives (at our gates/feeding into our lives during specific moments) make all the difference in how we come out of things on the other side. They help us to get things flowing in the right direction and keep thing out that shouldn't come in.
