We know it changes lives—ours and the people we’re reaching. At ChurchUnderground, taking action on your generosity is simple. The Bible teaches us a baseline standard for giving: the tithe. When we give the first 10% of our income to the church, we put God first in our lives. Tithing is an act of worship that expresses our gratitude, faith, and love for others. The Three-Month Tithe Challenge can help you get started.
