Again and again the great themes of biblical theology, of the Gospel, are illustrated not by specific discussions but by stories. That is why the concordance is not an infallible guide to what the Bible has to say on any given subject. For example, if you wanted to learn about faith you could find out a good deal by looking the word up in a concordance. But the concordance would not send you to this passage [2 Kngs. 6.16-17], because the word faith is not here, but the idea is. CKB
