Some people are very good at leading people to the Lord. Although everyone is exhorted by Paul to do the work of an evangelist (2 Timothy 4:5), there are those who have evangelism as a special gift. Some people are just gifted at sharing their 
faith with others and are often blessed with seeing people come to faith. Also, although everyone is exhorted to “give” and be generous, there are those whom God blesses in ways that make them exceptionally good at it (Romans 12:8). Usually what is included with those who have the gift of “giving” is the gift of “getting.” Some people are simply blessed with wisdom in the financial realm and know how to handle resources well and thus have gathered significant wealth. There aren’t many “rich” Christians, but there are some. That they have been blessed with God with the benefits of physical resources is evidence that God has also blessed them with the gifts of giving.
But that’s not the case with all those who have the gift of giving. Kathy and I are not rich and unfortunately we have not been as wise as we should have been on many occasions with our resources. Yet for 30 years or more we’ve given back as much as 30% of what God has given us. We currently give over 20 percent of our income to CBC and other Christian ministries we feel passionate about. I also think that God has blessed us with the gift of giving even though we don’t have great resources or great financial wisdom. It really is a “gift” to be able to give! It is one of the more joyful experiences in life. Furthermore, we’ve learned that you can’t out give God.
2 Corinthians 9:6 says, “Whoever sows sparingly will also reap sparingly, and whoever sows bountifully will also reap bountifully.” We reap materially. I’ve found that we can trust God to provide for us. I think He promised to do so in Philippians 4:19, “My God will supply all your need according to His riches in glory by Christ Jesus.” This statement is made in the context of the generous giving that the Philippians exhibited towards Paul. As “unspiritual” as this may sound, it’s been our experience that God richly blesses in physical ways those who are generous. Before becoming a Christian and before beginning our giving, we’ve lived miserly lives towards others and towards the Lord’s work in the world. We were always in debt! We always struggled with having way more month than we did money. But once we started giving God turned that around and we are living examples of the truth of Proverbs 11:24, “One gives freely, yet grows all the richer; another withholds what he should give, and only suffers want.”
