I understand what you are saying, and I somewhat agree, though I still always involve God in the conversation. The problem is that when you (I) do that we will never convince the other side of that our position has merit because they don’t believe in God or they believe in some fairytale version of who God is. I think the best we can do is pray that they allow His Holy Spirit into their hearts and opens their eyes.
Funny, that even the demons acknowledged Jesus as Christ, but not the secularists.
