If the deaths of Ananias and Sapphira is an indication of how God’s Holy Spirit deals with a sinful nature which tries to masquerade, then these fools claiming God as Jesus would coddle their degeneracy are in deep trouble.
You also have Elymas bar-Jesus the sorcerer as an example of those who don’t try to hide it. Never mind the rather sticky end of Herod after his impiety in Acts 12.
