Jesus replied, "Don’t you even yet know who I am, Philip, even after all this time I have been with you? Anyone who has seen Me has seen [God] the Father! So why are you asking to see Him [God]? Don’t you believe that I am in the Father and the Father is in Me? The words I say are not My own but are from My Father who lives in Me. And He does His work through Me. John 14:9-10 (TLB).
Jesus is the exact likeness and embodiment of the unseen God (Colossians 1:15). He perfectly mirrors God the Father and is stamped with God's nature (Hebrews 1:3). Jesus is the full expression of God in a human body and reveals God to us (John 1:18; John 14:9). He is the visible, tangible and physical image of the invisible God. Anyone who has seen Jesus has seen God the Father! (see also John 1:1-2). He is God-in-the-flesh (John 1:14).
Jesus explained to Philip, who wanted to see God the Father, that to know Jesus is to know God. In Jesus, God can be found. The search for God and truth ends with Jesus (See also Colossians 1:15; Hebrews 1:1-4). Jesus clearly stated at Hanukkah, “The Father and I are One” (John 10:30). Jesus and God the Father is not the same Person, but They are One in essence, nature and purpose. Jesus gives a clear picture of the very character of God (John 1:18; Philippians 2:6; Colossians 1:15).
Jesus is not only equal to God (Philippians 2:6), He is the eternal God (John 10:30, 38; John 12:45; John 14:1-11). Jesus worked with God the Father in creating the world (John 1:3; Colossians 1:16; Hebrews 1:2-3). He is Lord of all (Romans 9:5; Romans 10:11-13; Revelation 1:5; Revelation 17:14) and an expression of God’s glory (Hebrews 1:3; see also Exodus 16:7; Exodus 33:18; Isaiah 40:5). Jesus is God (see John 1:1, 14; John 14:9; John 20:28).
