Who is the designated Apostle of the Gentiles in the Church Age?
Paul is the designated Apostle of the Gentiles for the Church Age, the age of grace. His letters provide the fundamental truths for salvation, the Christian walk, and the local church, and are especially foundational for Gentiles. All Scripture is profitable, but these letters are central.
Les explains that for this age of grace, which is called the Church Age, Paul is the designated Apostle of the Gentiles. Therefore, the Pauline letters are where the fundamental truths for salvation, the Christian walk, and the operation of the local church are found. Les stresses that this does not mean the rest of the Bible is inappropriate, because Paul himself writes that all Scripture is inspired of God and profitable for reproof and instruction in righteousness. In Romans especially, there is much that is fundamental for Gentiles, and that is the reason they teach.
