bro, kasabot ka unsay pasabot sa word "God"? God is someone who has no equal or is anyong superior to him. How can God become Man and be under the laws of material nature if he is God? And again, the word SENT bro. Naay nagpadala nya dri. Jesus mentioned in clear words ha, You have not seen my Father's shape or form. Yet the people saw Jesus' shape or form when he spoke those words. Unsa pman angay study.han ana? Ka klaro na ana pgka.storyaha. Wa kakita ang mga tao sa porma sa Ginoo bsag si Jesus naa sa ilang atubangan nga nisulti ana. God does love us that he did send his Son to save us, by teaching how to love him and be happy, not by dying on the cross. If that was his original purpose, that verse would say " For God so loved the World that he sent his own Son to be crucified so that the world's sins would be erased." Would you, as a Father, be happy if I crucified your son and say that it is a "sacrifice" to your honor?
Your theories are no different from the impersonalists of India, who say that God forgot he is God and falls down to this material world. God then needs to meditate on himself to remember he is God and transcend the wheel of birth and death.
God is God, he is called God because he holds dominion over all, with no equal or superior in power. God can and will never be subject to his own laws. What you are doing is limiting his potency and power.
If you are saying Jesus came here to give his life for many, then I agree. But he did not give his life just so he could be crucified. If he had done so, what was the purpose for him to say that his first and foremost commandment is "that we love God with all our heart, all our mind, our entire being"? If his first commandment was to crucify him in order to release us from our sins, he would have SAID so. But he didn't.
And regarding Thomas saying that Jesus is God, Jesus is God in a sense because he is the MASTER at the art of Loving the Supreme Lord, not God the Supreme Controller. He is God the Servant, not God the Master. Who else better at knowing how to render loving service to the Supreme Lord than his representative?
"And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth(Matt. 28:1

." He was given power over Heaven and Earth, question is: who gave him that power?
And regarding your claim that only God has the power to forgive sins, then you are no different from the Pharisees that said that only God has the power to forgive sins, thereby denying Jesus' authority. A true servant of God has the power to forgive sins, since he/she is doing the will of the Supreme Lord without expecting anything in return.
