There is nothing in the sacred Scriptures to gratify an idle curiosity; but much that commends itself to the conscience, and that interests the heart. They are a mirror, into which he that seriously looks must, in a greater or lesser degree, see his own likeness, and discover what kind of character he is. That which was said of Jesus by the Samaritan woman, might be said of them, in thousands of instances: “He told me all that I ever did.” They are “the words of the wise which are as goads, and as nails fastened by the masters of assemblies.” They not only prick the sinner in his heart, but stick so fast that he is incapable of extracting them. It has been remarked, that they who heard the preaching of the apostles were generally moved by it, either to repent and be converted, or to oppose the truth with bitter resentment. Their doctrine was a savour of life unto life in them that believed, and of death unto death in them that resisted. Surely, if we preached more in the spirit and power of the apostles, the effects of our ministry would more resemble theirs, and our hearers would not be able to sit year after year easy in their sins. “The word of God is quick and powerful, sharper than any two-edged sword; piercing even to the dividing asunder of soul and spirit, and of the joints and marrow; and is a discerner of the thoughts and intents of the heart.” If our preaching be but little adapted to produce these effects, surely it contains but little of the word of God.
