In the Fourth Gospel, Jesus is better compared to Moses than to God. While in Matthew's Gospel, Jesus appears as a great teacher like Moses, in the Fourth Gospel, he appears as a great liberator/leader like Moses. Moses is sent to Pharoah like God (Exod 7:1; c.f., 3:10-11). His mission is to liberate the Israelites from their bondage in Egypt. For this purpose, he is given power and authorities. He acted like God for God. Otherwise, he is thoroughly an emissary sent by God.
Interestingly, in the Fourth Gospel, Jesus almost always emphasizes, if anyone wonders about his identity or work, that he is sent by God to do the work of God, which is none other than to bring the life and light to people in a chaotic world. He is given power and authorities to do this mission. Otherwise, he never claims that he is equal to God. The opposite is true. He says that God is greater than he (John 14:28). At other times, he says that "The father and I are one" (John 10:30). What he means is that he does the work of God; they are united with the common work. This is not the language of mutual equality, as commonly misunderstood. If I say that my family is one, I do not mean that all members are the same or equal. I mean that all are united in a family, loving and working together. Jesus's relationship with God is similar.
The conclusion is that the Fourth Gospel does not portray Jesus as God. Rather, he is better compared to Moses, who is sent by God to Pharaoh to deliver the Israelites from their bondage to Egypt. Jesus is also sent by God to do God's work in a dark world: to bring life and light to the world that God loved so much. Jesus is the Jewish Messiah who came to testify to the truth of God (John 18:37).
