These questions and many others are often asked to respected Christian financial counselor Larry Burkett. To answer them and help you understand the basics of financial giving, he has written Giving and Tithing.
We all know that it is better to give than to receive, but giving is much harder! Especially financially. Yet today's church needs physical and financial support from Christians. There are people who need God's help, and sometimes that help comes through the generosity of God's people.
Larry Burkett uses God's Word to explain church benevolence ministries, showing the strong biblical basis for giving and serving in the church. God uses Christians to minister in his name, and knowing that fact should encourage you to set up a plan to give back to God out of what He has given to you. At the same time, you will be opening yourself up to opportunities to help others and receive God's blessing.
