The tension is that we liked and were comfortable with our old life and our old flow but the new and better chapter God is writing does not need your old way or flow. One chapter must close before a new one can fully begin. Every new beginning comes from some other beginning's end. (Thank you Semi-Sonic from the song "Closing Time.") But it's true!
The tension is that we want to return to the way things were so we dedicate energy trying to rebuild the old when God is calling us into something new and better. Problem: when you are stuck in the old mindset, old expectation, and old vision for your life you cannot embrace the new blessings, new growth, and new purposes of the new destination.
