One of the problems for faith is that God is not something or someone that you can see: he is Spirit, which means he is invisible. How can you prove the existence of someone who is invisible?
In the first 18 verses of the Gospel of John chapter 1, a biblical passage that is often read at Christmas time, an answer is given to this issue. Later in the Gospel (chapter 4.24) Jesus himself teaches that “God is spirit”, so Christianity does not try to hide the fact that God cannot be physically seen.
Indeed, John 1 verse 18 acknowledges that “No one has ever seen God”, but the apostle goes on to bring a clarification that is absolutely mind-boggling: “the only-begotten God, [i.e. Jesus] who is at the Father’s side, he has made him known”. The more modern New Living Translation renders this as: “the unique One, who is himself God, is near to the Father’s heart. He has revealed God to us”. Let’s unpack that profound sentence.
The verb “beget” signifies the fathering of a child. The mother “gives birth”, and the father begets. The biblical expression “only-begotten” implies the unique communicating of divine life from the Father to the Son, Jesus. So Jesus teaches in John 5.26, “As the Father has life in himself” [i.e. divine life], “so he has granted the Son also to have life in himself”. This is unique to Jesus – the “only-begotten Son”. He uses this word himself in John 3.16: “God so loved the world that he gave his only-begotten Son, that whoever believes in him should not perish but have eternal life”.
So the “only-begotten God” is Jesus: he has made God the Father known. This is a major truth. The vital fact here stated is that: “Jesus has revealed God to us”. The word “revealed” brings us to a completely different level of reflexion on this difficult search for God. We have our ideas, (both small and confused and often far from correct) about God. But if God reveals himself – if the invisible becomes visible – we can have meaningful access to truth about him. This is indispensable if we are ever to know God. And this was one of Jesus’ essential roles in coming into the world.
Though we cannot see God in this life, he has shown himself in Jesus. That’s why Jesus could say, “Whoever has seen me has seen the Father” (John 14.9). In his sinless life of love, holiness, and compassion, Jesus showed forth the very nature of God. He lived among people who could realise that he was indeed “the image of the invisible God” (Colossians 1.15).
As we study the life of Jesus in the Gospels, we see God in human form. Or as Charles Wesley put it poetically: “Veiled in flesh the Godhead see / Hail the incarnate Deity / Pleased as man with man to dwell / Jesus our Emmanuel”. The biblical word Emmanuel means “God with us” (Matthew 1.23). That is who Jesus was – a totally unique incarnation of God. That’s why Christmas resonates with amazement and worship. For the only time in History, God entered the world as a small baby boy who grew up to live a sinless life, to teach about God as his Father, to do miraculous deeds, and when rejected and crucified, he rose triumphant from the dead and was seen and heard for forty days by hundreds of people before returning to heaven.
Nothing like that has ever happened elsewhere. God has revealed himself through Jesus. We do well to pay attention to his revelation.
