We can't force people to see things against their will. The Church just seems so obvious, necessary, and good to Catholics that we have difficulty understanding how others could see things differently. The first task of an apologist is to peer at the world through the eyes of the other.
We can't lead them to where we want them to be if we don't first find out where they are.
We can't speak to them unless we speak their language.
We can't answer their questions if we do not listen to their questions.
1 Tim 3:15: "Always be ready to give the reasons for the hope that is in you."
