If you had known me, you would have known my Father also. From now on you do know him and have seen him.”
Philip said to him, “Lord, show us the Father, and it is enough for us.” Jesus said to him, “Have I been with you so long, and you still do not know me, Philip? Whoever has seen me has seen the Father. How can you say, ‘Show us the Father’? Do you not believe that I am in the Father and the Father is in me? The words that I say to you I do not speak on my own authority, but the Father who dwells in me does his works. Believe me that I am in the Father and the Father is in me, or else believe on account of the works themselves.
John 14:7-11 (ESV)
The only way that we accurately know the Father is through knowing Jesus. God the Father and Jesus share one divine essence – “I and the Father are one” (John 10:30). God’s character and nature are on full display in Jesus. Jesus makes the Father known by His words and by His mighty works.
