How do we know Jesus is the way to know the Father?

In John 17:25-26, Jesus declares that He knows the Father and reveals Him to those whom the Father has given Him. This assertion exemplifies that Christ is the sole mediator and the perfect revelation of the Father. As stated in John 14:9, 'He who has seen Me has seen the Father.' Therefore, through knowing Christ, the fullness of God’s character and His righteousness is disclosed to us. Furthermore, only through the grace bestowed in Jesus can one truly understand and commune with God the Father, highlighting the importance of a personal relationship with Christ for spiritual knowledge and life.
