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. Entering into, engaging with, and departing from Christ's local body is a significant part of following Jesus.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. Ask family or friends to read your letter and offer suggestions. Fourth, when you leave, LEAVE. So, to my Central church family, I want to say, bless you, bless you, bless you, for you have been nothing but a blessing to us for 10 years.
