Why is it important that Jesus knows God completely?

The complete knowledge that Jesus possesses of God signifies that He is the ultimate revelation of the Father. In John 1:18, it is stated that the only begotten Son, who is in the bosom of the Father, has declared Him. This implies that without Christ, individuals cannot truly know God. His unique relationship as the Son of God means He knows the Father perfectly and thus can accurately reveal God's nature and will to humanity. This understanding is essential for salvation because it is through Christ that one comes to a saving relationship with God. The knowledge of God that Christ offers is not only intellectual but transformative, leading to eternal life, as outlined in John 17:3: 'And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent.'
