Jesus said this:
Truly, truly, I say to you, I am the door of the sheep. All who came before Me are thieves and robbers, but the sheep did not hear them. I am the door; if anyone enters through Me, he shall be saved, and shall go in and out, and find pasture. The thief comes only to steal, and to kill, and destroy; I came that they might have life, and might have it more abundantly. I am the good shepherd; the good shepherd lays down His life for the sheep. He who is a hireling, and not a shepherd, who is not the owner of the sheep, beholds the wolf coming, and leaves the sheep, and flees, and the wolf snatches them, and scatters them.
The wolves know the bible better than you do. They are not discrediting the bible, we have done that all on our own. No, the wolf is easy to spot, because they only do this, snatch and scatter. It is those who say that they are shepherds and are not, those are the ones who we are warned about. If we have wisdom, we can see the wolves. But the hirelings, those who are not concerned about the sheep, those are harder to see.
The only way to a strong foundation with and in Jesus is by fellowship with Him.
