The Bible asks us to give first, our first fruits to God. It is the one time in the Bible that God invites us to test Him.
"Test me in this … 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." Malachi 3:10 NIV
If you're not tithing already, a great way to start is with the Three-Month Tithe Challenge. It’s based on the promises of God in Malachi 3:10, and essentially it’s a money-back guarantee of sorts. It takes one of the greatest questions "What if?" out of the equation. This is often the biggest barrier that keeps people from experiencing the joy of giving.
