Giving away 10% of your income can be a big – and often frightening – commitment! That’s why we created the 90-Day Giving Challenge: a money-back guarantee of sorts. Essentially, it’s a contract based on the promises of God in Malachi 3:10-11. We commit to you that if you tithe for 90 days and God doesn’t hold true to His promises of blessings, we will refund 100% of your tithe. No questions asked.
