You will be enriched in every way to be generous in every way, which through us will produce thanksgiving to God. For the ministry of this service is not only supplying the needs of the saints, but it is also overflowing in many thanksgivings to God. 2 Corinthians 9:11-12.
Chapter nine here is a great reference passage to learn all about giving in the church financially. It also shows us a great way to worship God when we give with a good heart. In verses 1-5, Paul explains that he had such confidence in the Corinthian church that he said they would indeed give money.
