Tithing is a matter of faith - Neil L. Andersen

The Apostle Paul warned that the wisdom of men understands the things of men but has difficulty understanding the things of God. The world speaks of tithing in terms of our money, but the sacred law of tithing is principally a matter of our faith. Being honest in our tithes is one way we show our willingness to put the Lord first in our lives, above our own cares and interest. I promise you that as you trust in the Lord, the blessings of heaven will follow.

The faith required for the sacrifice of tithing has returned enormous amounts of blessings to me. So many, in fact, that I cannot count them all. So many that I haven't been able to receive them all. I highly recommend testing the promises of Malachi.
