God calls His children to be generous as He is generous. This is a tall order, since God loved us enough to give His own Son for us!!
While we may never be able to make that sacrifice for Him, we are obligated to give liberally of our finances and our time to Jesus and for the least of these. When we do this, though, God has promised to bless us right back, so that instead of losing money, we increase it through giving! What an amazing agreement! Not only that, but God will keep you afloat in times of famine, "rebuking the devourer" so that you may increase abundantly.
What a mighty God we serve!
