Let him rant, in doing so, those who follow this “enlightened” thinking will have a great awakening when he is finally comes off his lofty perch with an inevitable “come to Jesus” moment that we all experience in our lives.
Sadly, for many like him, the ‘come to Jesus moment’ happens AFTER death. And then they realize they were wrong...but it’s too late.
Not all have a ‘come to Jesus’ moment. If someone spits at God’s Grace and continues to hurl insult at God’s Christ Solution, the Bible is plain that He gives them up to their delusions, allows them to fester in their lusts.
