There are those that are wolves in sheep's clothing in the church.
This has occurred in history for centuries. It is absolutely true that there are leaders in our churches today that claim to be following Jesus with their whole hearts, but please know this is not entirely true.
They lay and wait and conceive ways in which to sway believers. It can happen to anyone, even other church leaders.
They all individually have their own motives. On the final day, we will surely see who they are.
