Let each one do just as he has resolved in his heart, not grudgingly or under compulsion, for God loves a cheerful giver. 2 Corinthians 9:7
This verse in 2 Corinthians tells us that God loves a cheerful giver. God wants us to give to our church, and to others freely so that we might experience the true joy of giving, and sharing with those around us.
I truly believe that not only does God love a cheerful giver, but that the act of giving will also make you more cheerful! When you give you experience the true joy of knowing you've made a positive impact on someone's life, and you acknowledge that there is something more important out there than money or material things. Hording everything you earn won't make you happy. True happiness comes through knowing Jesus Christ, and through living more like him – in an unselfish, caring and loving manner.
So next time you're thinking about whether or not you should give, remember. Giving makes you happier, and makes you a more un-selfish and caring person. Food for thought.
