There's only one place in the Bible where God told His followers to test Him. In the book of Malachai, 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 money. When it comes to our finances, what God really wants for 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 can 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 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 and in your life, we will refund 100% of your tithe from that 90-Day period. If you have questions, take a look at the FAQ's and guidelines below. You can also email Tiffany at
Let's trust Him and watch what He does.

I agree that for 90 days, I will contribute a tithe equal to 10% of my income. If I am not convinced of God’s faithfulness to transform my heart and life as a result of my obedience to His Word, then I may request a refund at the end of this period.
