James 5:16

Confess your faults one to another, and pray one for another, that ye may be healed.  The effectual fervent prayer of a righteous man availeth much.    

We will never be perfect no matter how hard we try, and we all have faults.  Jesus came to make us perfect and set us free from sin.  The body of Christ is there to help hold each other up and support each other.  Our fellow Christians offer encouragement and prayer when we need support.
