What does the Bible say about religion and truth?

In Mark 7:1-13, Jesus addresses the issue of religion, highlighting that the traditions of the Pharisees often contradict God's commandments. He emphasizes that true worship must come from the heart, not merely through adherence to rituals or man-made regulations. Jesus reveals that many who honor God with their lips do not truly worship Him because their hearts are far from Him. This passage illustrates that religion, as practiced by many, can dilute the pure truth of God's Word, making it essential for believers to discern between scriptural truth and human traditions.
