There are some of you that believe not. — Later, the word “disciple” became synonymous with the word “believer,” but there are those now following Him just as they would follow any Rabbi, and, regarding Him as a merely human teacher, they fall short of the faith which was the first qualification for true discipleship. They had heard, it may be, the Sermon on the Mount, and such teaching as that of Matthew 13. In part they could understand this, and therefore in part believed; but when faith was really needed, it was found not really to exist: for faith is accepting what is not demonstrable to the mere reason, and seeing what is invisible.
