John 16:30 - Clarke's commentary and critical notes on the Bible

Now are we sure that thou knowest all things, and needest not that any man should ask thee: by this we believe that thou camest forth from God. Now are we sure that thou knowest all things - Is not the following the meaning of the disciples? We believe that thou art not only the Messiah who camest out from God, but that thou art that God who searchest the heart and triest the reins, and needest not to be asked in order to make thee acquainted with the necessities of thy creatures; for thou perfectly knowest their wants, and art infinitely disposed to relieve them.
