Radical generosity is modeled by the early churches: "And now, brothers and sisters, we want you to know about the grace that God has given the Macedonian churches. In the midst of a very severe trial, their overflowing joy and their extreme poverty welled up in rich generosity." — 2 Cor. 8:1-2 

Jesus gave everything. He’s the ultimate example of radical generosity: "For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life." — John 3:16 

Riches eventually fail. God doesn’t. Radical generosity lives out this truth: "Teach those who are rich in this world not to be proud and not to trust in their money, which is so unreliable. Their trust should be in God, who richly gives us all we need for our enjoyment." — 1 Tim. 6:17 

God warned us about money. Radical generosity protects us from the love of money: "For the love of money is a root of all kinds of evil. Some people, eager for money, have wandered from the faith and pierced themselves with many griefs." — 1 Tim. 6:10

Radical generosity pays eternal dividends: “Don’t store up treasures here on earth, where moths eat them and rust destroys them, and where thieves break in and steal. Store your treasures in heaven, where moths and rust cannot destroy, and thieves do not break in and steal.” — Matt. 6:19-20
