The signals are crossed. Emotions are involved. The dream is at stake. In situations like this we need to hear from God clearly, and David is no different than you or I in this. He needs more than the approval of his friend; he needs to know what God is actually saying. When God then turns David's desire on its head in 2 Samuel 7, the promise is for more than just David. God's plan is a much bigger, multi-generational, eternal promise that includes you and me.
