C. S. Lewis wrote, before his spiritual conversion, to a friend. “The trouble with God, is that He is like a person who never acknowledges your letters and so, in time, you come to the conclusion either that He does not exist or that you have got His address wrong.”
After his conversion, he wrote, “What if God has already answered our letters and telegrams in His own love-letter written 2000 years ago, but we have not bothered to check our mailbox and discover it?”
Advice or words of warning must be spoken with a consciousness of our own common guilt. It is not to judge others or set ourselves up as moral judges of anyone; however, it is our duty to speak the warning words when they need to be spoken. We must never regard anyone as hopeless because of the changing power of Christ.
