Why is understanding true religion important for Christians?

True religion, as taught in Scripture, emphasizes salvation by grace through faith in Christ, contrasting sharply with the notion of achieving righteousness through works. This distinction is critical because it affects how believers relate to God and view their salvation. The example of the Pharisees, who outwardly claimed to serve God while their hearts were far from Him, illustrates the danger of self-righteousness. By understanding true religion, Christians can cultivate a genuine relationship with God, one that is rooted in His grace and the transformative power of the Gospel rather than in human effort or tradition. This is crucial for spiritual growth and assurance of salvation.
