How do we know that the Holy Spirit teaches us?

In John 14:26, Jesus promises that the Holy Spirit will teach believers all things and remind them of everything He has said. The work of the Holy Spirit is not limited to the apostles but extends to all who believe, as evidenced in Hebrews 8:11 where it's stated that they shall all be taught of God. This teaching goes beyond mere knowledge; it involves a deep understanding of God's truths that transform lives. Believers must actively seek this teaching as they engage with the Scriptures, trusting the Spirit to open their understanding and lead them into all truth.
