Malachi 3:10
Bring the whole tithe into the storehouse, that there may be food in my house. Test me in this,” says the Lord Almighty, “and see if I will not throw open the floodgates of heaven and pour out so much blessing that there will not be room enough to store it.

Giving is not really a financial issue, it’s a heart issue.  God will never truly have our hearts until he has our resources.  And we’ll never outgive or out-sacrifice God.  We’re so confident of this that we’ve set up the 90 Day Tithe Challenge.  Give 10% of your income for 90 days and if God doesn’t hold true to what He promises in Malachi 3:10, we will refund your money.  If at the end of 90 days if you haven’t gotten more from God than what you’ve given, we will refund your money.  No questions asked. 

Here’s what you do.  Sign up on the form.  Start giving - electronically, online, or with a check.  This allows us to keep track of everything.  At the end of 90 days, I’ll send you an email asking about your experience.  Be honest, tell me what God did during that time.  And if your answer is - he didn’t do anything.  We will refund all of your money.  No questions, no bother.  

That’s how confident I am in the Lord on this.
