What does the Bible say about knowing the true God?

In 1 John 5:20, it states, 'And we know that the Son of God is come and has given us an understanding that we may know Him that is true.' This understanding is vital because it affirms our relationship with God, rooted in the understanding of Jesus Christ as the true God and giver of eternal life. The knowledge of God is primarily revealed through the Scriptures, where we find the truths about His nature, His love, and His redemptive work through Christ, which is foundational for our faith as Reformed Christians.
