Don't be afraid of outgiving God. It is impossible to do that.

Swindoll’s line draws on a long Christian teaching about generosity and divine provision: believers need not fear that giving—whether money, time, hospitality, or mercy—will leave them ultimately impoverished, because God’s resources and faithfulness exceed human capacity. The phrase “outgiving God” frames giving as participation in a divine economy where grace is not scarce and where God’s giving precedes and surpasses ours. It also functions pastorally, addressing the anxiety that often accompanies sacrificial generosity. The claim is not a guarantee of immediate material return so much as an assurance that God’s care and recompense (in spiritual, communal, and sometimes material forms) cannot be exhausted by human liberality.
