It is possible to lose interest in a human interpretation of the Church, but not in God. If you have lost interest, allow God to refocus your vision. This refocusing will carry with it a new infusion of life and purpose that will help you see your circumstance with new clarity.
These seasons of dissatisfaction will not last forever if you are spiritually healthy. They are times of readjustment and realignment, not abandonment. There is a positive side to the dissatisfaction you are feeling. Your dissatisfaction with the status quo has made you hungry for something new. That new thing is not always a change of location, but a change of heart. Once God has your heart anything is possible.
