Thirteen books of the New Testament are letters attributed to the apostle Paul. We might imagine Paul sitting at his desk alone as he writes these thoughtful letters. Instead, Paul’s letters and his ministry were collaborative efforts. When possible, Paul brought others along to live and work with him. Some of these ministry partners were involved in physically writing several of Paul’s letters. Four other books—1 and 2 Timothy, Titus, and Philemon—were written to men that Paul had discipled. These men, in turn, discipled others. It’s a pattern established by Jesus, employed by Paul, and passed on to believers today.
