According to Trevin Wax, it’s no good to say this:
My purpose in meeting you is not any sort of conversion. I respect you and your beliefs. You’re not going to change, and I’m not going to change.
when you should be saying something like this:
I respect you as a person made in the image of God. I respect your right to hold to any faith that you choose. I would never coerce you or force my religious beliefs upon you, as such a practice would detract from the truth that you, like me, are made in the image of God. And yet, as a follower of Jesus Christ, I am commanded to share the gospel. When the time comes for me to seek to persuade you to follow Jesus, it is not out of a heart of oppression or desire for control, but out of love and concern. Since I truly believe the gospel offers hope for all humanity, I cannot keep it to myself. The gospel is too precious and you are too valuable for me to keep silent.
