What does the Bible say about true and false religion?

The Bible clearly illustrates that there are only two types of religion—true and false. True religion revolves around salvation by grace alone, through faith alone, in Christ alone. This is evidenced in passages where Jesus interacts with those who adhere to false religions, such as the Jews in John 5, who were focused on the law rather than on the grace and power of God manifested in Christ. Conversely, false religion emphasizes salvation based on human works and compliance with man-made rules, thus leading to spiritual blindness and judgment of those who obey God’s Word. In this context, true believers are those who have been given life by the Spirit of God and who witness His glory rather than adhering to dead rituals.
