Why is confessional faith important for Christians?

Confessional faith is central to the Christian experience; it reflects an agreement with God regarding His revelation in Scripture. In Romans 10:9, we learn that confession with our mouth and belief in our heart are key components of salvation. This confession indicates a sincere acknowledgment of Jesus as Lord and a recognition of His resurrection from the dead. Thus, our confessional faith not only demonstrates our understanding and acceptance of Christ's work but also aligns our hearts and lives with the truth of the Gospel, confirming that salvation is by faith alone through grace alone.
