It's fine to deal with people's doubts and explain why they have good reasons to believe in Christ. But until we tell them the good news of Jesus Christ, we haven't done our job. They need a saviour that God has provided them in Christ. Once they know that, we can do as much apologetics as we need to.

Of course, the only true response is heartfelt repentance and faith. However, if you don't feel the need to be honest in your presentation, then you will calibrate your presentation of the gospel to whatever gets the response you want.
