But his delight is in the law of the Lord; and in his law doth he meditate day and night.
This verse does not simply declare (as I have said elsewhere) that those who fear God are blessed; it equates religion with the study of the law. It teaches that God is rightly worshiped only if his Word is obeyed. Therefore, men are not free to model a religion, each after his own idea. The standard for religion must be taken from God’s Word.
The law only is mentioned here: but we are not to suppose that the rest of Scripture is ignored, since all of it is really an interpretation of the law and so is included under that title. The prophet is commending the law with its supplement. Indeed, as I just said, the faithful are here urged to read The Psalms.
But the first thing required of the faithful is delight in the law of the Lord. These words show us that compulsory or slavish worship is not at all acceptable to God. Only those who come happily to the study of the law, who enjoy its teaching, who think nothing more worthwhile or pleasanter than to make progress in it, are qualified students of the law.
From this love of the law comes constant meditation on it, as the prophet immediately adds. Only those inspired by this love can devote themselves to its constant study.
