Fast from Your Church
You can fast from church completely, but for many of us a better fast is to break from our own church for a season. Being consumed in the life of your church is a wonderful thing, but it can also make for a busybody. So visit other churches during Lent. Take a tour of witnesses to Christ, and especially darken the doors of churches you never thought you'd visit. Attend a Catholic mass, a megachurch service, and meetings at the Baptist, Lutheran, Methodist, Quaker, Assemblies of God, Vineyard, and nondenominational churches in your town.
Look for churches where the people don't look like you--the Gospel is colorblind, and you will be, too, after you meet the full array of brothers and sisters in Christ.
