What is the significance of the Holy Spirit being called the 'Spirit of Truth'?

The designation of the Holy Spirit as the 'Spirit of Truth' indicates His role in revealing and applying the truth of Scripture to the hearts of believers. In John 14:17, it is stated that the world cannot accept Him because it neither sees nor knows Him, but believers are granted the privilege of knowing Him. The Holy Spirit helps believers understand God’s truth, emboldens them to live according to it, and reminds them of Christ's teachings. This guidance is essential for spiritual growth and for navigating a world filled with confusion and deception.
