How then will they call on him in whom they have not believed? And how are they to believe in him of whom they have never heard? And how are they to hear without someone preaching? And how are they to preach unless they are sent? As in is written,"How beautiful are the feet of those who preach the Good News!"... Faith comes from hearing, and hearing through the word of Christ.
-Romans 10:14-15,17
God is generous and so he calls us to be as well. What we do with what God has given us shows the world where our hearts are at and helps proclaim the gospel. We want to glorify God with every area of our lives, and that includes what we do with our finances.
