John 10:27 My sheep listen to my voice; I know them, and they follow me.
Jesus was talking to the Jews who had gathered to hear what He would have to say about why they thought He was making people doubt!
What makes any of us doubt? Is it not the difference between what you are hearing and your own beliefs?
Jesus was trying to tell the Jews the truth directly from God; they were not about to change the beliefs they had built up in their own minds…
We need to be open to what Christ is going to ask of us and willing and humble to do His will.
