Blessed is the man Who walks not in the counsel of the ungodly, Nor stands in the path of sinners, Nor sits in the seat of the scornful; But his delight is in the law of the Lord, And in His law he meditates day and night. He shall be like a tree Planted by the rivers of water, That brings forth its fruit in its season, Whose leaf also shall not wither; And whatever he does shall prosper.
~ Psalm 1:1-3 (NKJV)
Being duly affected with the malignant and dangerous nature of sin, the transcendent excellencies of the divine law, and the power and efficacy of God’s grace, from which our fruit is found, we must teach and admonish ourselves, and one another, to watch against sin and all approaches towards it, to converse much with the word of God, and abound in the fruit of righteousness and, in praying over them, we must seek to God for his grace both to fortify us against every evil word and work and to furnish us for every good word and work.
~ Matthew Henry, Commentary on Psalm 1:1-3
