Sin is something we all have to deal with in our lives. We were born sinners, with a sin nature. You only need to look at the willfulness of a small child to see they came that 
way with a rebellious, willful nature built inside. It was not something they learned. However, as we grow we learn to sin even more by fulfilling our own desires. Adam and Eve fulfilled their own desires in the garden of Eden when they willfully sinned against God by eating of the forbidden tree, the tree of good and evil.
Each of us needs to come to the realization that we are sinners and approach God with a 
repentant heart asking Him to forgive us through faith in Jesus Christ. Our faith in Jesus allows us to be cleansed and made whole. However, we still have that sin nature within us and we need to grow and learn about Jesus, depend upon Him and stay repentant to walk with Him by faith. Our heart’s desire is to walk with Jesus and grow more and more like him. Sanctification describes this process in our lives and it is the work of the Holy Spirit within us that enables us to grow stronger in Christ and sin less.
David knew the key to a clean and whole existence with God was to be repentant and humble, confessing his sins to God. Psalm 32 describes David’s thoughts about this:
Blessed is the one whose transgression is forgiven, Repentance brings blessing.
whose sin is covered.
2 Blessed is the man against whom the Lord counts no iniquity,
and in whose spirit there is no deceit.
3 For when I kept silent, my bones wasted away Being unrepentant can cause
through my groaning all day long. you physical illness.
4 For day and night your hand was heavy upon me;
my strength was dried up as by the heat of summer. Selah
5 I acknowledged my sin to you, David resolves to repent with
and I did not cover my iniquity; an openness to God.
I said, “I will confess my transgressions to the Lord,”
and you forgave the iniquity of my sin. Selah
Psalm 51:1-2, 10 David knew that God alone was able to forgive sin and lays his sins before Him. He knew he was unworthy of forgiveness but trusted God in his infinite mercy to forgive him.
Have mercy on me, O God,
according to your steadfast love;
according to your abundant mercy
blot out my transgressions.
2 Wash me thoroughly from my iniquity,
and cleanse me from my sin!
He knew God alone could create a new heart within him.
Create in me a clean heart, O God,
and renew a right spirit within me.
What about you? Do you know the truth and reality of 1 John 1:9 ? “If we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness.” This is a promise we can claim and depend upon. God is faithful and will keep His promise to forgive all our sins. All we need to do is confess and have a repentant heart before Him.
Practice repentance daily for a closer walk with Jesus.
