tithe

Protestants gave more of their income to churches in the Great Depression than they do today.

---> what does that say about where our treasure is?

"Why don't people ask us about our hope? The answer is probably that we look as if we hope in the same things they do. Our lives don't look like they are on the Calvary road, stripped down for sacrificial love, serving others with the sweet assurance that we don't need to be rewarded in this life. Our reward is in heaven (Matthew 5:12)!... If we believed this more deeply, others might see the worth of God and find in Him their gladness"
~John Piper, Don't Waste Your Life
