The man who hears Christian teaching, and never gets beyond hearing, is like “a foolish man who built his house on the sand” [Matt. 7:26]. He satisfies himself with listening and approving, but he goes no further. He flatters himself, perhaps, that all is right with his soul, because he has feelings, convictions, and desires, of a spiritual kind. In these he rests. He never really breaks off from sin, and casts aside the spirit of the world. He never really lays hold of Christ. He never really takes up the cross. He is a hearer of truth, but nothing more.
