I will behave myself wisely in a perfect way. O when wilt thou come unto me? I will walk within my house with a perfect heart.
Psalm 101:2 moves from David’s song to David’s life. Before he speaks of removing wicked men from his kingdom, he puts himself under examination. He will behave wisely, choose a perfect way, pray for God’s presence, and walk uprightly inside his own house. This is a king speaking to God about personal holiness before public government. The order is searching. David does not begin by correcting servants, neighbors, enemies, or subjects. He begins with himself. A man who would rule others rightly must first rule himself under God.
“I will behave myself wisely.” David resolves to govern his conduct by wisdom. Scripture had already described him in these very words: “And David behaved himself wisely in all his ways; and the LORD was with him” (I Samuel 18:14; see also I Samuel 18:5,30). Wise behavior and the LORD being with him stand together in that history, which prepares naturally for David’s prayer, “O when wilt thou come unto me?” Wisdom begins with God: “The fear of the LORD is the beginning of wisdom” (Psalm 111:10). David therefore seeks not cleverness, political skill, or reputation, but conduct ordered beneath the fear and presence of God.
“In a perfect way.” “Perfect” here does not mean David claimed sinless perfection. It describes an upright, complete, sincere way before God, a course not divided between outward profession and inward rebellion. David elsewhere prayed, “Teach me thy way, O LORD; I will walk in thy truth: unite my heart to fear thy name” (Psalm 86:11). A perfect way is whole-hearted rather than double. It refuses selective obedience, where a man honors God in chosen matters while protecting rebellion elsewhere.
This phrase presses integrity. David cannot demand truth from others while tolerating deceit in himself. He cannot punish immorality publicly while excusing secret lust privately. He cannot require loyalty from subjects while dealing falsely with God. “The integrity of the upright shall guide them: but the perverseness of transgressors shall destroy them” (Proverbs 11:3). Public conduct, private conduct, speech, thoughts, worship, family life, and judgment should agree under one rule. A divided life is not a perfect way.
“O when wilt thou come unto me?” This is prayer to God. David interrupts his vow of conduct because wise behavior and a perfect way are not sustained by self-confidence. He wants the Lord Himself to come to him in fellowship, help, and blessing. God had promised concerning appointed worship, “in all places where I record my name I will come unto thee, and I will bless thee” (Exodus 20:24). David therefore does not seek a well-ordered life apart from God. He asks for the presence of the One whose wisdom and favor alone can make the vow worth keeping.
Moses had made the same issue decisive: “If thy presence go not with me, carry us not up hence” (Exodus 33:15). Success without God is failure. A disciplined house without His favor is poor. David is king, but kingship cannot replace communion with Jehovah. He wants the Lord near while he walks the way he has vowed to walk.
“I will walk.” David returns from prayer to duty. “I will walk” describes continuing conduct, the ordinary course of life rather than an occasional act. God commanded Abram to walk before Him and be perfect (Genesis 17:1). David makes the same kind of practical resolution. Holiness is proved by repeated obedience in ordinary circumstances. Grace does not make a man passive; it teaches him “that, denying ungodliness and worldly lusts, we should live soberly, righteously, and godly, in this present world” (Titus 2:12).
“Within my house.” David brings the vow home. The house is where public appearance loses much of its power. Family, servants, and close companions see what strangers do not. A man may maintain an honorable public name while those nearest him know another character. David says his perfect walk must survive that test. Paul later required a bishop to be “one that ruleth well his own house,” asking, “For if a man know not how to rule his own house, how shall he take care of the church of God?” (I Timothy 3:4-5).
David’s later history adds a fearful warning without changing the meaning of this vow. When he departed grievously from such conduct, God said, “Now therefore the sword shall never depart from thine house; because thou hast despised me, and hast taken the wife of Uriah the Hittite to be thy wife” (II Samuel 12:10). Even a man after God’s own heart could not keep his house by resolution alone. A strong vow must be joined to grace, watchfulness, fear, and continual dependence upon God.
“With a perfect heart.” David ends where conduct begins, in the heart. He does not want external order hiding internal corruption. A perfect heart is whole, sincere, and directed toward God without protected rebellion. David later charged Solomon to know the God of his father and serve Him with a perfect heart and willing mind, because the LORD searches all hearts and understands the imaginations of the thoughts (I Chronicles 28:9). God sees farther than the household sees.
This guards the entire psalm from hypocrisy. Strong discipline with hidden lust is corruption. Public zeal with private bitterness is corruption. Correct judgments with a proud heart are corruption. “Keep thy heart with all diligence; for out of it are the issues of life” (Proverbs 4:23). David will soon regulate his eyes, companions, servants, and kingdom, but the first kingdom needing order is within. A perfect household cannot be built safely around a divided heart.
Jesus Christ alone walked perfectly without qualification. He always did what pleased the Father (John 8:29), and as a Son He is over His own house (Hebrews 3:6). Those whom He legally justifies are accepted wholly upon His finished work and God’s grace, not because they reproduce His perfection. Yet grace calls them to follow Him: “For even hereunto were ye called: because Christ also suffered for us, leaving us an example, that ye should follow his steps: Who did no sin, neither was guile found in his mouth” (I Peter 2:21-22). Every man who rules a house under the Son should fear to govern it by another standard.
Begin reform with yourself. Behave wisely, walk in a perfect way, pray for God’s presence, and make your own house the first field of consistent holiness. “Search me, O God, and know my heart: try me, and know my thoughts” (Psalm 139:23). Rule nothing confidently until your own heart and house are consciously under the rule of God.
I will behave myself wisely in a perfect way. O when wilt thou come unto me? I will walk within my house with a perfect heart.
