For since the creation of the world God's invisible qualities - his eternal power and divine nature - have been clearly seen, being understood from what has been made, so that men are without excuse. Romans 1:20
In truth, there is no man who will get to the end of his life without knowing God is real. Any man who claims he never saw Him is a fool and a liar. He is evident in all of creation. No man can truly refute His existence.
Recently, I saw an interview with Rick Warren, the author or "The Purpose Driven Life" and pastor of Saddleback Church in Southern California. Interestingly, he stated that for the first several months he was in California he simply knocked on doors and talked to people about God and the church. He commented that in all his knocking, he didn't find one atheist. Not one! In Southern California?! Every person he met believed in God, yet most were disillusioned with the church.
My guess is that even the most vocal atheists tend to doubt their beliefs at times.
My son has a college professor who gained national notoriety when he refused to provide recommendation letters for students who would not acknowledge evolution as fact. It has been an interesting lesson for my son - to sit in a class with a brilliant teacher who has been dooped by the enemy. Even this man will someday be surprised when God asks, "Did you know Me and My Son?"
Lord, continue to reveal Yourself to the world. Forgive us for denying You. Bring Your children out of the shadows into the light, so that those trapped in the darkness might find hope. Change the hearts of the lost. Soften the heart of my son's teacher.
