John 3:2

John 3:2. And said unto him, Rabbi, we know that thou art a teacher come from God: for no man can do these miracles that thou doest, except God be with him.

This was good reasoning on the part of Nicodemus. If he did not at first go as far as he afterwards did, it argued well for him that he went as far as he could. O thou who art troubled with unbelief, believe as much as thou canst; and then cry, "Lord, I believe, help thou mine unbelief; and, especially, help me to get rid of it." Confess to Christ what thou dost believe, and he will add more to thy belief.
