And the angel of the Lord solemnly assured Joshua, 7 “Thus says the Lord of hosts: If you will walk in my ways and keep my charge, then you shall rule my house and have charge of my courts, and I will give you the right of access among those who are standing here. This is a repeated theme in the Bible that just can't be said enough. Do what God says, God's desires will be done through you. We can see Israel's struggle and the obstacles they faced. I know my own obstacles... like that sinking feeling that maybe what God wants from me is not going to be comfortable, or that I might misunderstand what he wants, or that I might make big sacrifices that in the end don't amount to much. Mostly, the solution is always faith, trust, surrender.
