The following day he arrived in Caesarea. Cornelius was expecting them and had called together his relatives and close friends. As Peter entered the house, Cornelius met him and fell at his feet in reverence. But Peter made him get up. “Stand up,” he said, “I am only a man myself.” Acts 10:24-26
Popularity is the enemy of humility. It makes you think you are better than you really are. The Apostle Peter rejected anyone worshipping him, falling to their knees. He understood his humanity.
Being famous comes with all kinds of temptations. Many Christian pastors, writers and entertainers have succumbed to those temptations and fallen hard in the public eye. Their failures show the unbelieving world that Christianity is no better than atheism.
On the other hand, being famous means you are making an impact. You are reaching people with your message. You must live under public scrutiny.
Famous Christians need to surround themselves with fellow believers who keep them accountable and in check. Most of all they need to remember they were saved from their sins just like the people they reach.
