Sirona,
My thoughts on this:
In Exodus 4:16 and 7:1 God Almighty tells Moses that he, Moses, would be "as God" to Aaron and to Pharoah. Moses had the authority of God when he spoke to both Aaron and Pharoah but he was obviously not the God Almighty.
The OT speaks of a greater Moses that was to come this one is identified by Peter as the Christ, the Son of God, Acts 3:22. Jesus though spoke with the authority of God not as a mere man as Moses was but rather as a Son, one who is the exact representation of the Father. His name, Immanuel, signifies that very well because to see the Son was to see the Father. But never did the Son say he was equal to the Father. Everything God is the Son is also but one, God himself!
If Jesus were God equal to the Father one would have to jump hoops to explain not only 1 Corinthians 15:28 (quoted below) but also all the many NT statements that clearly position the Father above the Son both during his lifetime and after his resurrection. The OT and NT use of the word "God" is much more sophisticated than the way it is used today. Religious fundamentalists try to make everything black and white, God on the other hand has made a world, spiritual and physical, of endless color and shade. He wants us to use our reasoning minds. Jesus is not God and yet Jesus is God for to see him and to know him is to see God and to know God.
1 Corinthians 15:28, "When all things are subjected to him, then the Son himself also will be subjected to the One who subjected all things to him, so that God may be all in all." nasb
