The best thing to do is to explain the reasons for leaving so that the church is not hurt or mystified as to why you are leaving. Be honest, be upfront, and be loving and gentle.Keep your former church in your prayers and speak well of it. We love each of you so much, and are very sad to say goodbye. We have grown so much during our time here. Create and write an official letter to announce your departure from a church. Download finished copies as PDFs. Try to leave graciously. I did leave, and am now in a new place much better for me. Thank you, thank you, for all you've done, for your sweet heart for the Lord and for your neighbors.
