Psalms 51:1
Have mercy upon me, O God, according to thy lovingkindness: according unto the multitude of thy tender mercies blot out my transgressions. Have mercy upon me, O God, according to thy lovingkindness: according unto the multitude of thy tender mercies blot out my transgressions.
It is the plea of a guilty king after grievous wrongdoing to be pardoned out of God's unfailing love and abundant compassion, with every offense wiped away. True repentance makes no excuse and seeks no escape, but owns the sin, humbles the heart, and declares God right in judging and merciful in forgiving. The cry asks for more than release from guilt, longing for a cleansed soul-temple, a pure heart, and restored fellowship with God. When the sinner humbly confesses and turns, God forgives, erases the record of sin, and restores the wanderer to covenant favor through the blood of Christ and the cleansing of the Holy Spirit. It therefore stands as an urgent call to come to God at once without delay or self-saving, trusting His power alone to wash, sanctify, and keep, with assurance that every fallen one who returns and yields may take courage and begin again.
Words and Historical Setting
The prayer asks God to show mercy in line with His lovingkindness and to blot out transgressions in line with the multitude of His tender mercies. It is the prayer of David, the exalted and honored king of Israel, after departing from righteousness and transgressing God's law in great sin. That sin included his wrong against Uriah and his wife, and the prayer came when the Lord's message of reproof reached him through His prophet Nathan.
After his sin he turned directly to God as his best friend and Creator rather than to a priest, pleading with trust and hope for pardon. Pardon is sought from the Creator because wrongs done to other people also reach back to God. His plea also asked God to cleanse him from sin, seeking more than pardon alone.
His confession was unconcealed and public, a penitential sacred song recounting his sin and repentance and his hope of pardon through God's mercy. It was sung by all Israel in public assemblies before the court, with priests and elders and judges and princes and men of war and lords present. He did not conceal his guilt even though he knew it would bring his guilt to the notice of other generations, but desired that others might be instructed by the sad history of his fall and that knowledge of his fall be preserved to the latest generation.
True Repentance Explained
The verse teaches true repentance for sin and lays out the course to take when departed from the Lord. It confronts people with how far they fall short of the purity and Christlikeness God requires, and its lessons must be taken to heart. A merely nominal profession does not refine and sanctify the life, but leaves influence worthless like salt without savor. Sincere repentance makes no attempt to excuse guilt or escape judgment, but rests its hope on God's mercy. It confesses sin, humbles the heart, declares God to be just in all His dealings, and accepts God's decision as just and merciful.
David's response was in dust and ashes, with deep humility and sincere repentance. He poured out the soul in penitence and humiliation, with fear and trembling at the word of the Lord under rebuke. He did not turn against the prophet who reproved him. This stood in contrast to the rulers of the surrounding nations, who would have taken the life of the faithful reprover. He trusted God rather than people who excused unrepented sin, feeling he could endure the loss of his crown but could not be deprived of God's favor, so that his need for God's favor mattered more than keeping his crown.
True repentance requires realizing the enormity of sin. It keeps the transgression ever before the mind and does not repeat the offense. The changed life it produces is not merely a passing response to emotional excitement. The mercy and compassion asked from God are given on that condition, and to repeat the same sin after reproof would forfeit compassion. The sinner recognizes that sin has polluted the soul and the soul-temple, and that only God can cleanse it and save it from ruin.
The plea therefore seeks more than pardon, longing also for cleansing, a clean heart, purity, and restored communion with God. The verse expresses genuine repentance toward God and faith in Jesus Christ in the midst of human struggle and temptation. It shows one burdened with guilt pleading for mercy through Christ instead of giving up to despair. Sincere repentance and confession are accepted by God even though the transgressor still suffers for the transgression.
Forgiveness and Present Call
God's mercy and forgiveness can blot out transgression, erasing sins from His remembrance and from His book of remembrance. After confessing wrongs and making restitution as far as possible, people may ask God to do what they cannot do for themselves, to forgive and erase sin. That asking rests on the assurance that there is forgiveness with God, by which the sinner is justified by the blood of Christ and sanctified by the cleansing power of the Holy Spirit.
When the sinner becomes penitent and humble after rebuke and punishment, the Lord forgives and restores to covenant relation with Himself. David felt he could endure the loss of his crown but could not be deprived of God's favor. His need for God's favor mattered more than keeping his crown.
The verse directs the sinner to seek God humbly without delay, speculation, or hesitation for mercy, pardon, and conversion so that sins may be blotted out. It means coming after opening the heart to Satan, defiling the soul-temple with buyers and sellers and idols, trying to save self and finding self held by an unbreakable power and unable to cleanse one stain of guilt. It means bringing the sinful polluted soul to God, laying it at His feet and trusting it to no power but His, recognizing that sin has polluted the soul-temple and that only God can cleanse it and save it from ruin. It means asking to be washed in the blood of the Lamb, clothed with garments of purity and righteousness, sanctified through truth, given the Spirit and love in the heart, inclined to keep the commandments, united in will to God, and cleansed and kept as His temple. It is especially the prayer for those who have long resisted light and opposed righteousness, acknowledging many sins and iniquities that have separated them from God, to humble the heart, cease stubborn resistance, and confess.
The verse stands through all ages as encouragement for fallen children of God to take courage, repent, and try again to walk in the way of God's commandments, showing one burdened with guilt pleading for mercy instead of giving up to despair. The Lord knows how strong the inclinations of the natural heart are and will hear and help in every time of temptation, and that same mercy is still extended to the sinner who returns and heeds the pleading voice of the Spirit. Those who humble themselves and turn from resistance to light can be forgiven, converted, and transformed.
