These four letters from Paul were written to men whom he considered to be his sons in the faith. In 1 Timothy and Titus, Paul gave practical explanations of church order. In 2 Timothy, he taught believers how to relate to the truth of God. In Philemon, he set a wonderful example how believers should relate to one another as he appealed to Philemon on behalf of Onesimus. These letters are valuable, instructive, and applicable to all members of God's family. Paul is the perfect individual to give this instruction because of his calling as an apostle and his close relationship to the early Christian church. All who study these letters should find them extremely beneficial as they guide each of us towards Christian maturity!
