Doesn't work that way. Being insincere causes insincerity. I remember when I was at the VA one night and they were kicking everyone out of the emergency room because all attempts to revive a man was failing who had just had a heart attack. There was a crowd around him of so called professionals, nurses telling him much of your philosophies, doctors taking turns with charges and others pumping on his chest all while talking to each other in a nonchalant fake rooting for you manner. He was flatlined when a cop asked me to leave, but I put my hand towards the cops chest as a stop hand turned to an OK gesture and flipped the other hand extended palm up towards the man and called on the Lord of Hosts in silent prayer, I wasn't disappointed. Only one nurse got it and smiled. That is how it works. Sincerity for God literally judges hearts.
