Is there value in apologetics if it does not lead to evangelism?

I wonder if “apologetics” which does not lead people to Christ as Savior, and then on to their living under the Lordship of Christ in the whole of life, really is Christian apologetics. There certainly is a place for an academic study of a subject called “apologetics,” as the defense and the credibility of Christianity, but if it does not lead the students to use that material to lead people to Christ as Savior, one can ask its value.
