It may be difficult for you to decide whether or not you have what it takes to teach adults at your church. Many people feel that they do not have the expertise to minister to adults, but you don't have to be perfect or know every last detail about the Bible to teach. There are no degrees or certificates that qualify someone as an adult Sunday school teacher. There are, however, great rewards for teaching adults, and you can be certain that those in your class will truly appreciate both your time and your effort.
