Why this examination? We'll let the INC answer this question:
"...all religious people should be stirred to inquire about
the status of preachers in their respective churches. It is their bounden
duty, for the sake of their souls, to ascertain if the founder or leader
of their church was sent by God or not."
"The right to preach the Gospel comes from God, not from
any man or any human institution. It is the people's privilege and right
to question the authority of anyone preaching the gospel".
It's our privilege and right to examine the claims of
the INC; our eternal destiny lies in the balance.
