No man hath seen God at any time; the only begotten Son, who is in the bosom of the Father, he hath declared him (John 1:18).
In both the Gospel and the first letter that bear his name, John affirms that no man has ever seen God (John 1:18, 1 John 4:12, 20). This seems to be a most baffling statement considering everything else that John is trying to teach, and, for that matter, what has been revealed in the Old Testament. How can John say that no one has ever seen God after saying that the Word was God and the Word became flesh (John 1:1, 14)? Didn’t Jacob wrestle with God (Genesis 32:28-30)? Didn’t Moses see God’s back (Exodus 33:18-23)? This is a conundrum indeed!
We should not believe that John is terribly inconsistent and ignorant of the Old Testament. He understands what he has written earlier in the Gospel, and he knows what is revealed in Genesis and Exodus.
Instead, John is trying to get us to understand a profound truth. As Jesus says, “God is spirit” (John 4:24). In that form, as He truly is, no man has seen Him nor can see Him. Humans have only seen manifestations of God – His glory, His power, and/or His messengers, the angels. Jacob most likely wrestled with an angel. Moses, no doubt, saw God’s glory. Jesus the Word is truly God in the flesh, but no man can see the spirit in Him.
But if no man has ever seen God, how can we know about God? This is the focus of John’s statement in John 1:18 – even though we have not seen God, we can know all about God, because we can know about Jesus the Word.
John says that the Son, Jesus, has declared God. The word translated declared involves the idea of relating or telling a story (cf. Acts 10:8, 15:14, 21:19). According to John, therefore, the very nature and essence of God is related to us through Jesus.
But how can this be so? Jesus explains it for us in John 14:6-11. He boldly declares that if you have seen Him, you have seen the Father (John 14:9). The Father is “in” Jesus, and the words Jesus speaks and the deeds Jesus does are from the Father (John 14:10-11).
As Paul will say, Jesus is the “image of the invisible God,” in whom “dwelleth all the fulness of Godhead bodily” (Colossians 1:15, 2:9). If we want to understand what God is like, all we need to do is consider Jesus. As God is love, so Jesus loved (1 John 4:8, John 13:1). As God is just, so Jesus will be the judge (Matthew 25:31-46, Romans 2:5-10). As God is the Creator, so through Jesus were all things created (Genesis 1:1, John 1:1-3, Colossians 1:15-17).
A lot of people have a very negative picture of God the Father. They imagine Him as a cantankerous old man with a long white beard who sits in Heaven all day trying to figure out new and inventive ways of smiting people and condemning them. Yet many of these people have a much more favorable view of Jesus, picturing Him as the loving Savior of the world, the Good Shepherd laying down His life for the sheep.
We haven’t seen God. Nevertheless, it should be clear that God is not a cantankerous old man, but instead a loving Father who wants to bless His children (cf. Romans 8:1-39). We know this because we can see Jesus through what is revealed of Him in the New Testament, and when we have seen Jesus, we have seen the Father. We know of God because Jesus has made Him known. Let us praise God for His great love and care, and seek to reflect His attributes in our own lives (cf. 1 John 2:3-6)!
