"Now here is what I want to do: Build a temple in honor of God, my God, following the promise that God gave to David my father, namely, 'Your son whom I will provide to succeed you as king, he will build a house in my honor.'
David wasn't able to build a temple because God had something else in mind for him. God called David's son, Solomon, to build the temple.
What are we not able to do because we've been called to something else? Are we holding onto an old dream with a death grip and not able to see a new dream God has for us?
Old dreams can get in the way of new ones.
