In this verse, and the following verses, the Holy Spirit leads Paul to give a magnificent description of Jesus as to his person and activities. In doing so, the apostle gives answers to important questions that would have been asked by his contemporaries about Jesus.
First, Paul says that Jesus is the exact image of the invisible God. He means that, in Jesus, the invisible God who cannot be seen was seen by his creatures. His description refers to the incarnate Christ and his mission on earth. The idea is like the statement by the apostle John when he said of Jesus that ‘No one has ever seen God; God the only Son, who is at the Father’s side, he has made him known’ (John 1:18). Or we can think of Jesus’ self-description when he told Phillip that ‘Whoever has seen me has seen the Father’ (John 14:9).
As Calvin put it, ‘he is revealed to us in Christ alone, that we may behold him as in a mirror. For in Christ he shows us his righteousness, goodness, wisdom, power, in short, his entire self. We must, therefore, beware of seeking him elsewhere, for everything that would set itself off as a representation of God, apart from Christ, will be an idol.’
It is possible to see some of God’s attributes through looking at the creation. As Paul says in Romans 1, in creation we can see God’s power in that he made the universe and sustains it in existence. We can also deduce that since he is the creator of all things he existed before all things that he made. It is also possible to conclude from harvests that God the creator reveals his goodness to his creatures.
Yet the revelation of God in creation is limited as far as we are concerned. Creation does not tell us that God is triune, that he is love, that he is merciful, that he is full of pity, as well as many other details about him. We cannot discern God’s plan for the creation merely by looking at the creation.
Jesus, however, revealed those truths about God. He told us that God is Father, Son and Holy Spirit. Through his explanations connected to his acts of kindness, he showed that God is full of compassion and mercy. By giving himself to die on the cross for our sins, he revealed that God is love, that he gave his Son for that purpose. His giving himself showed that God had a plan of salvation, a plan that intends to bring sinners into his family, to sanctify them by his Holy Spirit, and to bring them to dwell in God’s presence for ever. He also revealed that God will judge those who rebel against him, and that the Judge will be Jesus himself.
When he calls Jesus the image of the invisible God, Paul does not suggest that Jesus is somehow inferior to God. Rather, when he came to reveal the Father, it was the Creator who had entered our world. He did not cease to be divine when he became human. Yet he did reveal more about God when he came and did so because he was and is God. The Son of the Father’s love became man to show us his Father.
