Why is it not enough for Christians to know God?

The distinction that it is not merely about our knowledge of God, but about His knowledge of us, is essential in understanding our relationship with Him. In Matthew 7:23, Jesus says, 'I never knew you: depart from me, ye that work iniquity,' highlighting the futility of religious works without a genuine relationship with God. Knowing that we are known by God gives us the assurance of His love and grace, marking us as a part of His covenant people. This truth assures believers that their relationship with God is rooted in His sovereign choice and not in human effort, reinforcing the centrality of grace in the gospel.
