That which defines Yahweh as a God is much different than that which defines Jesus as a god... despite the tendency of Christians to describe them as One.
Jesus did not create the Universe and the Earth. Jesus did not expel Iblis from the ranks of Angels nor did he banish Adam and Eve from Eden. Jesus did not slaughter countless humans in the Old Testament with fire, wind, ice, earth, water, disease, famine, angels of death, wicked spirits, summoning/compelling animals, compelling other humans to commit murder, empowering humans with godlike strength, death by the Ark, etc, etc, ETC!
Jesus did not get angry and destroy 99.9% of humanity in one big ass flood. Jesus did not nuke Sodom and Gomorrah. Jesus did not chill with Moses at the top of a mountain and threaten to destroy all the people that were just freed from Egypt. Jesus did not turn Moses' nephews to ashes for burning the wrong incense. Jesus did not grant Solomon his wish and Jesus did not send his only begotten Son to die for your sins. I can go on.
God/ YHWH/ Allah/ Adonai is a Master of creation and a Master of destruction. God is "perfect" in the sense that God is the most powerful lifeform there is.
Jesus' archetype is more about what you people perceive as "Good"... things like unconditional love, humility, virtue, redemption, sacrifice, forgiveness, deliverance, salvation, happiness...
In the Bible, Jesus is passionate but not so passionate that he goes around consuming people in fire and turning people to ash when he is disrespected or challenged. Jesus instead uses wisdom to spread his positive message to the World, with the occasional Miracles, and looks for the "good" in even the lowest of people, encouraging them to seek redemption.
I believe in Jesus but there are obvious differences between Christ and YHWH... despite whatever connection it is that makes them like "One".
