Paul founded the Church at Corinth on his second missionary journey in A.D. 50 -51. While he was in Ephesus on his 3rd missionary journey, he received some negative reports concerning the morality of the believers there. He immediately sent Timothy to correct the situation at Corinth. He also wrote this letter to the church, probably thinking that it would arrive before Timothy got there. The members of the church were starting to return to the old ways of idol worship. In particular, the immorality with the temple prostitutes and overindulgence in both food and drink. But, if we read verse 2 very carefully, we find that under the guidance of the Holy Spirit, Paul wrote this letter to me and you. It reads: “to those sanctified in Christ Jesus and called to be his holy people, together with all those everywhere who call on the name of our Lord Jesus Christ—their Lord and ours.” That includes us and we should take it as a stern warning not to go back to our old ways. While we may not have shrines where all types of immoral acts are carried out, we have more than enough idols of our own making. Each one of us needs to take a few minutes and ask God the Holy Spirit to reveal to us the idol(s) that are standing between us and our God.
8 If we claim to be without sin, we deceive ourselves and the truth is not in us. 9 If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness. 10 If we claim we have not sinned, we make him out to be a liar and his word is not in us.–1 John 1:8-10 (NIV)
