God has given you a spiritual gift, and it is not the same as a natural ability. That natural talent, rightly sanctified for God’s use, often points toward the identity of your spiritual gift. But you should find out the special gift God has given you while you’re serving as diligently as you can without that definite information. In fact, in addition to the study of Scripture, the best way to discover and confirm which spiritual gift is yours is through serving.
