Confession is hard because you have to admit that you were wrong, at fault, the one responsible, or guilty. Confession is vital, but God also wants repentance. You can confess what you did and never feel bad or guilty. Until you do, you will never repent and change. God wants you to turn from your sin(s) toward Him and a righteous life.
Confession in a prayer can lead to a repentant heart that can be used by God to do some wonderful things in the world. When you confess your sins in prayer you release them to God. When you do so with a repentant heart you find forgiveness. God will forget your sin ever existed because He is merciful and He loves you.
God's justice is truth. Sin will be punished, but only the unrepentant heart will suffer eternally. Jesus showed us this truth in his short life as a human. He endured and showed us how to love like God. He was nice to spare feelings. He was kind by speaking truth. He never lied. He called sin sin. He forgave those who were repentant and held those who were not accountable. Repentance leads to forgiveness and acceptance from God.
A confessional prayer with a repentant heart leads to atonement then a life change. It is powerful. It is beautiful. It leads to refreshment in your life. There is nothing bad or negative about confession with a repentant heart. The end result may not be what you want in life, but it does set you free. Confess your sins to God, then those that love you if needed, lastly those that you may have harmed or hurt. Take responsibility for you own life and the choices that you make.
