[a]Blessed [fortunate, prosperous, and favored by God] is the man who does not walk in the counsel of the wicked [following their advice and example],
Nor stand in the path of sinners,
Nor sit [down to rest] in the seat of [b]scoffers (ridiculers).
But his delight is in the law of the Lord,
And on His law [His precepts and teachings] he [habitually] meditates day and night.
And he will be like a tree firmly planted [and fed] by streams of water,
Which yields its fruit in its season;
Its leaf does not wither;
And in whatever he does, he prospers [and comes to maturity]. – Psalm 1:1-3
Kidner concisely summarizes the force of verse one when he writes, “Counsel, way and seat (or ‘assembly,’ or ‘dwelling’) draw attention to the realms of thinking, behaving and belonging, where a person’s fundamental choice of allegiance is made and carried through.”65 I believe the progression in these three areas of believing, behaving, and belonging, can be illustrated in the Book of 1 Corinthians. The Corinthian church was far from spiritually mature. When Paul sought to correct the evils in this church which had been reported to him (1:11-12), he first dealt with the errors in their thinking. The first three chapters of 1 Corinthians concern the vast difference between merely human wisdom and the wisdom of God. The Corinthians were guilty of worldly reasoning, and not using godly wisdom. The wisdom of the apostles was the wisdom of God and totally different from worldly wisdom (2:1-9). The wisdom of God can only be known through revelation (2:10) and can only be understood through the ministry of the indwelling Holy Spirit (2:11-16).
Delight in spiritual things evidences grace; it is a sign we have received the spirit of adoption. A sincere child delights to obey his father. He who is born of God, is ennobled by grace, and acts from a principle of sincerity; grace alters the bias of the heart, and makes the stubborn rebellious heart, into a willing heart. The Spirit of grace is called a free Spirit, Psalm 51. not only because he works freely—but because he makes the heart free and cheerful in obedience; a gracious heart does not act by constraint—but by free consent. Thomas Watson
Scripture is so powerful and true that it crowds out and eliminates the harmful and false arguments, information, images, and even our deepest motivations that could otherwise assume power in our lives. It is when our minds wander while daydreaming or sleeping, unfettered by the straight jacket of our rational thoughts, that we are most led by our hearts. It is then that our imaginations, dreams, recurring thoughts and obsessions reveal themselves. This is where we really live. A healthy heart that has been amply stocked and fed with the rich nourishment of God’s Word, fully indwelt by His Spirit, becomes the dominant director of our souls renewing our minds.
