Thomas Watson on the necessity of meditation:
The end why God has given us his word written and preached, is not only to know it – but that we should meditate on it. The scripture is a love letter which the great God has written to us. We must not run it over in haste – but meditate upon God’s wisdom in writing, and his love in sending it to us. Why does the physician give his patient a remedy; is it only that he should read it over and know the remedy – or that we should apply it? The end why God communicates his gospel remedies to us, is, that we should apply them by fruitful meditation.
