2 Corinthians, Paul’s second letter to the Corinthians sets forth the apostle’s great love for the brethren. Everything that Paul did was for the benefit of the Corinthians. Paul’s great desire for these brethren was that their spiritual restoration. The Corinthians; however, needed to clear three major hurdles to achieve restoration.
Firstly, the Corinthians needed to identify and pray for the forgiveness of their sin of being unwilling to forgive one who seeks forgiveness.
Secondly, the Corinthians needed to clear themselves from sharing unlawful affections with unbelievers such as uncleanness, fornication, and lasciviousness and finally the Corinthians needed to be restored for being deceived by divisive brethren who were teaching false doctrines and making faulty accusations against Paul.
"Now faith is being sure of what we hope for and certain of what we do not see."
