John 12:35-36

John 12:35-36. Then Jesus said unto them, Yet a little while is the light with you. Walk while ye have the light, lest darkness come upon, you: for he that walketh in darkness knoweth not whither he goeth. While ye have light, believe in the light, that ye may be the children of light. These things spake Jesus, and departed, and did hide himself from them.

When people determine to reject Christ, he leaves them; why should he tarry where he is rejected? He "departed, and did hide himself."
