Paul writes this second letter to the church in Corinth from Macedonia while on his way to Corinth. This is one of the most personal of all his letters, he expresses both how exciting and how painful his life as a missionary has been.He also finds it necessary to defend himself against those who are criticizing him. This is something that God has taught me ... keeping quiet sometimes harbors more problems. As you read this letter, think about how exciting it can be to serve the Lord, but realize too that being a Christian can sometimes lead to pain and suffering.
