Very interesting article from an unexpected source ... a financial management expert who specializes in wealth management and retirement.
I passionately believe in tithing -- the practice of giving a tenth of your income to your church or mission, or to charity. It's a simple idea but not so easily accomplished; only an estimated 5 percent of Americans actually tithe.
My story begins with a legacy of grandparents and parents who faithfully tithed and taught me at an early age to do the same. Even before owning my wealth management company, I remember interning at a financial firm at the age of 14 and observing that the families who seemed to enjoy the most blessed lives were those who were faithful and obedient. Not all of them were wealthy, but they had everything they needed.
Wealth comes in many forms. Money can buy you a house, but it won't buy you a home. Money will you buy you a bed, but it won't buy you a good night's sleep. Money will fill the offering plate, but it won't fulfill you or save you. Those early experiences helped frame my world perspective on placing a priority on tithing.
The easy answer to "Why tithe?" is because it works and God tells us to do this in Malachi 3:10. "Bring all the tithes into the storehouse, that there may be food in My house, and try Me now in this," quotes the Bible. "If I will not open for you the windows of heaven and pour out for you such blessing that there will not be room enough to receive it."
