Giving isn't about depriving ourselves. It's about investing in eternity. God promises that our gift is a seed into an eternal fund.
"Do not store up for yourselves treasures on earth, where moths and vermin destroy, and where thieves break in and steal. But store up for yourselves treasures in heaven, where moths and vermin do not destroy, and where thieves do not break in and steal. For where your treasure is, there your heart will be also." - Matthew 6:19-21
