Why is the distinction between true and false religion important for Christians?

The distinction between true and false religion is vital for Christians because false religions often lead people away from the grace of God, emphasizing human works instead of Christ's finished work. True religion asserts that salvation is by grace alone, through faith in Christ alone, which brings true hope and security. Understanding this difference protects believers from being deceived by doctrines that undermine the sufficiency of Christ in their lives. By recognizing false teaching as a manipulation of God's grace, Christians can steadfastly hold to the true Gospel, thus ensuring their faith remains rooted in the sovereignty and perfect righteousness of Christ.
