One way to love God, love people, and serve the world is by giving.
"Each of you should give what you have decided in your heart to give, not reluctantly or under compulsion, for God loves a cheerful giver. 2 Corinthians 9:7
"Where your treasure is, there your heart will be also." Luke 12:34
"Give and it will be given to you." Luke 6:38
"Bring the whole tithe into the storehouse, that there may be food in my house. Test me in this," says the LORD Almighty, "and see if I will not throw open the floodgates of heaven and pour out so much blessing that there will not be room enough to store it." Malachai 3:10
