"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. But his delight is in the law of the Lord; and in his law doth he meditate day and night. 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 ungodly are not so: but are like the chaff which the wind driveth away. Therefore the ungodly shall not stand in the judgment, nor sinners in the congregation of the righteous. For the Lord knoweth the way of the righteous: but the way of the ungodly shall perish."
I love this psalm. It describes so well the character of a righteous person. I use this psalm as a personal standard, and for self analysis to see how I am doing as a disciple of Christ. The blessings of this psalm especially give me comfort – "He shall be like a tree planted by the rivers of water...whatsoever he doeth shall prosper."
Have you ever seen trees that grow along riverbanks? Their roots are thick and strong, and well established through the ground. They grow tall and beautiful because they have an unending supply of water. That is what we can be like when we plant ourselves in the Gospel's fertile soil. We are forever watered and nourished by Christ's atonement and mercy, which is like a river of water that never dries up. This is what I want to be like.
