This may sound so simple...
But maybe that's why we as Christians take advantage of it.
Why is confessing sins so powerful?
It forgives us and cleanses us from all unrighteousness.
"If we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness." (1 John 1:9)
Walking forgiven and cleansed as a righteous man or woman of God is walking in freedom.
"Blessed are the pure in heart, for they shall see God." (Matthew 5:8)
Confessing sins creates a pure heart in us.
How often should we confess our sins?
Not just once a week. Not just once a month.
I believe if you recognize the power of this blessing you will start confessing your sins every night.
When you don't confess sins it gives the devil power over your emotions or thoughts in that area of your life.
What else can confessing sins do for us?
"Confess your trespasses to one another, and pray for one another, that you may be healed." (James 5:16)
Confessing sins heals us.
Don't hold it in. Confess it to God or someone that God leads you to and be set free.
