Completely sold out to the King
1 Blessed is the man that walketh not in the counsel of the ungodly, nor standeth in the way of sinners, nor sitteth in the seat of the scornful.
2 But his delight is in the law of the Lord; in his law doth he meditate day and night.
3 And he shall be like a tree planted by the rivers of water, that bringeth forth his fruit in his season; his leaf also shall not wither; and whatsoever he doeth shall prosper.
4 The ungodly are not so: but are like the chaff which the wind driveth away.
5 Therefore the ungodly shall not stand in the judgment, nor sinners in the congregation of the righteous.
6 For the Lord knoweth the way of the righteous: but the way of the ungodly shall perish.
In this life, the godly, or the blessed, man is not immune from trials. Many are the storms which assail him here. But his roots are not of himself. The graces of the Spirit–faith, hope, and love– are of God and, therefore, indestructible. "Who shall separate us from the love of Christ?" A famous preacher once said that the dead tree often broke in the storm, while the living tree, well-nourished from hidden sources, withstood every storm, however severe and prolonged. Rooted and grounded in Christ the righteous shall endure to the end. The Psalm shows that the godly man is united to Christ in the totality of his nature. Mind, heart, and will rest upon Him alone for salvation.
