I saw Larry King interview with Joel. Joel fell into the double bind that Larry sets all all conservative people of faith who appear on his program. If Larry's victim declares the exclusive claims of Jesus Christ and the Gospel, Larry gets to demonize him as a narrow minded bigot. If the victim soft peddles the gospel he cashes in chips with his core constituency and sends an I'm OK/Your OK message to the very people who need to be confronted with the claims of Christ. What's a fellow to do? Stay off the Larry King show? That might be the best solution. Or the conservative christian community might come up with stand reply such as, "You know more important than my opion is what Jesus said--He said, I am the way the truth and the life, no one come unto the Father but buy me. I'd encourage you to look into that and decide for yourself what He meant".
If one is a true Christian,there should be no hesitation in stating that they believe that the Word of God is the truth, and that only those who obey the Gospel of Jesus Christ are going to Heaven. They should not care what Larry King thinks or says about them. The only thing that matters is what God says.
Stand up for truth and accept the consequences.
