Many congregations who need to transform are afraid of losing members, and thus lower expectations of members so they will not feel any pressure to leave. Others push the commitment button and say if members are faithful they will attend more and give more money.
Both approaches are wrong.
What works is the belief that a Christian congregational community is the best Christ-centered, faith-based form for seeking a deeper relationship with the Triune God that brings joy and exhilaration. With this spiritual focus it is effective to increase expectations of people to engage in spiritual formation and missional engagement.
