How do we know the doctrine of knowing God is true?

We can ascertain the truth of the doctrine of knowing God through biblical revelation. In John 17:3, Jesus clearly states that eternal life is knowing God, indicating that this intimate knowledge transcends mere intellectual understanding. Moreover, the entirety of Scripture supports this, wherein the knowledge of God is coupled with the understanding of His holiness and grace, outlined in the redemptive work of Jesus. Thus, our assurance lies in the consistent biblical testimony that reveals God as both knowable and relational through Christ.
