To repent is to realize that all your thinking (your entire view about reality) was wrong – and then to see and submit to God’s truth…
My son, do not forget my teaching,
but let your heart keep my commandments,
for length of days and years of life
and peace they will add to you.
Let not steadfast love and faithfulness forsake you;
bind them around your neck;
write them on the tablet of your heart.
So you will find favor and good success
in the sight of God and man.
Trust in the LORD with all your heart,
and do not lean on your own understanding.
In all your ways acknowledge him,
and he will make straight your paths.
Be not wise in your own eyes;
fear the LORD, and turn away from evil.
It will be healing to your flesh
and refreshment to your bones.
Honor the LORD with your wealth
and with the firstfruits of all your produce;
then your barns will be filled with plenty,
and your vats will be bursting with wine.
My son, do not despise the LORD’s discipline
or be weary of his reproof,
for the LORD reproves him whom he loves,
as a father the son in whom he delights.
Have mercy on me, O God,
according to your steadfast love;
according to your abundant mercy
blot out my transgressions.
Wash me thoroughly from my iniquity,
and cleanse me from my sin!
For I know my transgressions,
and my sin is ever before me.
Against you, you only, have I sinned
and done what is evil in your sight,
so that you may be justified in your words
and blameless in your judgment.
Behold, I was brought forth in iniquity,
and in sin did my mother conceive me.
Behold, you delight in truth in the inward being,
and you teach me wisdom in the secret heart.
Purge me with hyssop, and I shall be clean;
wash me, and I shall be whiter than snow.
Let me hear joy and gladness;
let the bones that you have broken rejoice.
Hide your face from my sins,
and blot out all my iniquities.
Create in me a clean heart, O God,
and renew a right spirit within me.
Cast me not away from your presence,
and take not your Holy Spirit from me.
Restore to me the joy of your salvation,
and uphold me with a willing spirit.
Then I will teach transgressors your ways,
and sinners will return to you.
Deliver me from bloodguiltiness, O God,
O God of my salvation,
and my tongue will sing aloud of your righteousness.
O Lord, open my lips,
and my mouth will declare your praise.
For you will not delight in sacrifice, or I would give it;
you will not be pleased with a burnt offering.
The sacrifices of God are a broken spirit;
a broken and contrite heart, O God, you will not despise.
Do good to Zion in your good pleasure;
build up the walls of Jerusalem;
then will you delight in right sacrifices,
in burnt offerings and whole burnt offerings;
then bulls will be offered on your altar.
