How do we know the doctrine of spiritual understanding is true?

The doctrine of spiritual understanding is rooted in biblical teaching, particularly in Jesus' exhortation that we must have spiritual ears to truly hear and understand God's Word. In instances like Revelation 2:7, repeated calls to hear suggest that spiritual comprehension is a divine gift. The Scriptures assure us that if our ears are opened by God, we can discern His truth, which is not merely theoretical but evidenced by life changes we experience, such as a true hatred for sin and a love for Christ. This transformation is a testament to the work of the Holy Spirit in believers’ lives, affirming the crucial nature of spiritual understanding.
