I agree @oluwatobilola. Preacher's kids are really expected to be superhumans full of perfection and holiness. This places a huge responsibility on their shoulders to live up to other people's expectations of them.
The same applies to preachers too. Just think back to the case of Apostle Suleiman's scandal and how the media blew it out of proportion. Any man could have done those same things and gone scott-free.
On the other hand too. I think its because of this saying;
To whom much is given, much is expected.
Cheers dear!
you are right, thanks for stopping by @nairadaddy
