Mark Driscoll gives some helpful hints how to determine if one has the gift of evangelism:
* Do you enjoy being with non-Christians and sharing the gospel?
* Are you able to effectively communicate to non-Christians in a language they can understand?
* Does a person’s conversion bring you profound joy?
* Do you feel frustrated when you haven’t shared your faith for a while?
* Do you enjoy teaching others how to share their faith?
* Do you find it easy to direct a conversation toward the topic of Jesus Christ?
While I find the questions helpful, admittedly my understanding of whether one has the spiritual gift of evangelism or not essentially boils down to this one question: when you share the gospel with an unbeliever in Jesus, does God the Holy Spirit so bless your endeavors by granting repentance and converting people to genuine faith in Jesus?
I realize there are obvious sticking points with reducing it to this one question (e.g. Christians must always guard the tendency to share the gospel message in ways that ensure a desired response). However, should not every Christian aspire for all six questions to be normative in ones life? If not, I fear many Christians may simply retort, “What do you expect? I don’t have the spiritual gift of evangelism anyway (unlike so-and-so).”
