According to Your love and kindness;
According to the multitude of Your tender mercies,
Blot out my sins.
Wash me thoroughly from my iniquity,
And cleanse me from my sin.
And my sin is always before me.
Against You, You only, have I sinned,
And done evil in Your sight—
That You may be found just when You speak,
And blameless when You judge.
And in sin my mother conceived me.
You desire truth inside of me,
And in the hidden part You will make me to know wisdom.
Wash me, and I shall be whiter than snow.
Make me hear joy and gladness,
That the bones You have broken may rejoice.
Hide Your face from my sins,
And blot out all my iniquities.
And put a steadfast spirit within me.
Do not cast me away from Your presence,
And do not keep Your Holy Spirit from me.
And uphold me by Your generous Spirit.
Then I will bear witness of Your ways,
And sinners shall be converted to You.
The God of my salvation,
And my tongue shall sing aloud of Your righteousness.
And my mouth will praise you.
You do not desire sacrifice, or else I would give it;
You do not delight in burnt offering.
The sacrifices you ask of me are a broken spirit,
A broken and a repentant heart—
These, Lord Jesus, You will not despise. – Psalm 51
The Bible tells us in that if we say we have no sin, then we deceive ourselves and the truth is not in us, but if we confess our sins He (Jesus) is faithful and just to forgive us our sins and cleanse us from all unrighteousness. Ground yourself in the Word of God and abide in Him through prayer, thanksgiving and in the assurance that Jesus will keep His promise of salvation as you grow in grace.
