Three things are notable about this man:
1. His company. "He walketh not in the counsel of the ungodly, nor standeth in the way of sinners, nor sitteth in the seat of the scornful."
2. His reading and thinking. "His delight is in the law of the Lord, and in His law doth he meditate day and night."
3. His fruitfulness. "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."
The river is the Holy Ghost; the planting, the deep, abiding life in which, not occasionally, but habitually, we absorb the Holy Spirit; and the fruit is not occasional, but continual, and appropriate to each changing season.
His life is also prosperous, and his spirit fresh, like the unfading leaf. Such a life must be happy. Indeed, happiness is a matter of spiritual conditions. Put a sunbeam in a cellar and it must be bright. Put a nightingale in the darkest midnight, and it must sing.
