You can


There’s only one place in the Bible where God told his followers to test him. In the book of Malachi, when teaching about generosity, God said, “Test me in this and see if I will not throw open the floodgates of heaven.” But it’s not about the money. When it comes to our finances, what God really wants from us is our hearts and our trust.

Tithing—a giving principle that teaches us to give the first 10% of our income to the local church—is one of the most tangible ways we worship God. It declares that He is first in our lives and opens our hearts to His plans. If you’re not tithing already, a great way to start is with the 90-Day Tithe Challenge. We believe wholeheartedly that God blesses those who live generously, so we want to issue a challenge: Tithe for three months and see what happens. If you don’t start to see a transformation in your heart or in your life, we will refund 100% of your tithe. No questions asked. (If you have questions, take a look at our refund FAQs or email — we’re here to help!)

Let’s trust Him and watch what He does.


Our prayer for you is that God will begin to work in your life in a way that causes your heart to overflow with God’s love and grace, that it transforms your life, and that it deepens your faith and trust in him. But God’s blessing might not come in a blank check in your mailbox. Keep your eyes and hearts open so that you don’t miss seeing God’s provision and faithfulness in your life.

After you sign up to take the challenge, we’ll send you resources and encouragement. We would also love to hear your story along the way—how is God blessing you after taking this next step in your faith?


Learn how to get rid of debt, manage your money, and spend and save wisely through an upcoming Rock Solid Finances class. This biblical, nine-week course will give you practical steps to get from where you are to where you’ve dreamed you could be.
