Why is the heart of the Apostle Paul important for understanding Romans?

In Romans 1:1, Paul refers to himself as a "slave of Jesus Christ," which is central to grasping the essence of his message throughout the book. This identification as a servant reflects a heart of humility, highlighting that his teachings are not driven by personal ambition but by a desire to faithfully communicate God’s truth. By acknowledging his position as a slave, Paul sets the tone for the entire epistle, directing attention away from his credentials to the divine authority of the message being presented. This servant mentality is essential as it encourages believers to approach the teachings of Romans with reverence and readiness to submit to God’s authority, and to understand that any rightful authority in the church must always lead back to Christ, the ultimate Master.
