What does the Bible say about knowing God and Jesus Christ?

According to John 17:3, eternal life is defined as knowing the only true God and Jesus Christ, whom He has sent. This knowledge is not merely intellectual but relational, highlighting the importance of a personal relationship with God through Christ. To know God means to recognize His sovereignty, holiness, and the redemptive work of Jesus, encapsulating the essence of salvation and eternal life. This understanding underscores the centrality of Christ in all matters of faith and worship.
