Just like today, the Christ followers of Paul’s time needed to know that they were being obedient to God’s will. Unfortunately for them, they didn’t have easy written access to God’s direction. Fortunately for them, however, they had the apostle Paul. As he and other of the New Testament authors wrote their letters, these provided instruction to the church assemblies of that day. Pastor Mark is reminding us that just as Paul’s various letters were inspired by God and used to bring maturity to the disciples of that day, those same letters will help us mature as well – if we make use of them.
