Paul, called to be an apostle of Christ Jesus by the will of God, and our brother Sosthenes,
2 To the church of God in Corinth, 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:
3 Grace and peace to you from God our Father and the Lord Jesus Christ. 1 Corinthians 1:1-3
First and Second Corinthians were written to address significant moral and spiritual leadership problems that the Corinthians were experiencing. They were still a fairly young church, but as often is the case, problems arise out of fairly immature leadership. There is a vigor and enthusiasm with youth, but there is also immaturity.
When starting a new book of the Bible, it’s helpful to read the entire book to get an overview of what the author is trying to convey. As an example, why is “the Love chapter”, 1 Corinthians 13 where it is in the Bible? It’s a medium-sized book so reading it in chunks throughout the day should help.
As you read, look for areas in the 21st century church that are similar to the church in Corinth, and those areas that are different.
