As obedient children, do not be conformed to the passions of your former ignorance, but as he who called you is holy, you also be holy in all your conduct, since it is written, “You shall be holy, for I am holy.” (1 Peter 1:14-16).
Christians are called to destroy the sin in their lives and to become Holy like God. Sin is forgiven when it is confessed to God alone:
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)
An accountability partner is someone who helps us to wrestle with sins that are affecting our daily lives or relationships. Each person in the partnership holds the other responsible for goals that they set to move away from sin. They celebrate their victories and confess their failures.
Therefore, confess your sins to one another and pray for one another, that you may be healed. The prayer of a righteous person has great power as it is working. (James 5:16)
