Poor Paul…he so loves the Corinthians who were baby believers in the faith. He had previously spent 18 months with them ...testifying to the gospel of Christ and encouraging them in the love, grace and knowledge from God. They had eaten together, studied together, cried together and no doubt loved each other. During this time, he watched them grow in their faith and built fellowship through their shared love of Christ. But once he left, he received word of problems in Christian conduct within the walls of the church. He writes 1 Co dealing with the importance of developing holy character, which wasn’t received very warmly from the Corinthians. He went back to them as a result of these problems to deal with them in person. Paul referred to this visit as a ‘sorrowful visit.’
‘All this is from God, who reconciled us to himself through Christ and gave us the ministry of reconciliation: that God was reconciling the world to himself in Christ…And he has committed to us the message of reconciliation.’ 2 Co 5:18-19.
