From a Homily on ​The Will of the Righteous in the Will of God

St. Nikolai Velimirovic

"But his delight is in the Law of the Lord and on His Law doth he meditate day and night"  (Psalm 1:2)

"...The mind is the rudder of both the will and the heart.  If the mind is permanently directed toward God, then it will eagerly meditate day and night on the Law of God, and will not walk in the counsel of the ungodly (Psalm 1:1) but will seek the truth and the revelation of all that is in God's Law.  If the mind is so directed to God, then, swiftly, the heart and will of man will also be directed toward God.  Then the will, as the implementing organ of the inner man, will carry out only what is in accordance with the will of God and what is written in the Law of God.  Then man will not stand in the way of the sinners (Psalm 1:1), and will not sit in the seat of the scornful (Psalm 1:1); he will not commit sin, nor will he draw other men to sin.  At the beginning of this Psalm, the Prophet David praises the man who does not commit three specific evils, and now he continues to praise him when he does two good things.  The three evils are:  to seek wisdom of a sinner, to live the life of a sinner and to corrupt others by one's evil example.  The two good things are:  to conform one's will completely to the Law of God; and to direct one's mind to meditate day and night on God's Law.

O my brethren, how lamentably shallow are the minds of all those who do not know the Law of God!  The depth of man's mind is measured by the depth of his knowledge of God's law.  The mind of him who meditates on the mysteries of God's law is deep, wide and exalted; and the mind is the rudder of the heart and will. ..."
