What does it mean to corrupt God's Word?

To corrupt God's Word means to distort, dilute, or misinterpret its intended message. In 2 Corinthians 2:17, Paul contrasts true preachers with those who corrupt the Scripture, pointing out how false preachers may add to or take away from biblical teachings. This includes using various corrupt versions or applying Scripture universally rather than contextually. Such corruption leads to misconceptions about God's nature and His will for humanity, which is harmful to the church and individual believers.
