Paul had a deep concern for the Christians in the churches, which he planted. This is something that is very obvious in the second letter to the church in Corinth and the letter to the Galatian churches. Pauls integrity was being attacked by intruders in Corinth, and he needed to defend himself in order that Christians there would not be destabilized in their faith. One of the things that stands out very clearly is Pauls pastoral heart and care for these Corinthian believers. The letter to the churches in Galatia was also written, following the unsettling effects of intruders into the churches. Wrong doctrine was being taught, and the Christians were in danger of being completely led away from the fundamental message of the gospel that salvation is by grace through faith. As we look back from our position in the twenty-first century, we can be thankful for Pauls uncompromising approach to the gospel.
