This is very good debate with four very intelligent speakers , and each one with different opinions. This video gives you lots of things to consider.
Was that a "book quote" you just snuck in there?I don't understand repeatedly quoting book, chapter and verse to people in this type of setting who say they've already looked at it and have rejected it. But I see well meaning christians doing it quite often. I respect the non believers views more than to try and argue, beg or plead them to repentance.
My 'job' as a christian is not to ensure you get saved. It's the Holy Spirit's job to soften and prepare the heart of the non believer. My 'job' as a christian is to present the Law and follow His example. Every true believer is compelled to do that. But not to chase and plead with people when they're clearly not open or ready, (Luke 16:31). You'll do a lot more watering and nurturing than harvesting in this world.
Remember there are four types of people (soil). But only one of those types ultimately makes it. If that realization doesn't break your heart, you're already dead.
