Wow, many opinions, suppositions and theory here ! I can only respond to these with Biblical scripture. Unfortunately those who do not see scripture as the true word of God will not be convinced of my evidence therein, be it as it may, I will do my best before God and with humbleness try to approach these questions for you utilizing the only way I have been given authority to do so.
I see the big problem you are having with the God of the bible is why? Why would God need to sacrifice his son for sinners? Or why If he can do all by only his voice, did he go this route? Indeed God could ! The problem with this is where is the justice? Given what we know of a Holy God who cannot look at sin, who is a righteous judge, who gave us his holy laws and the punishment of breaking said laws, would we as a created people see his righteousness if he just said OK, I forgive you ?
Let us look to life as we know it and imagine a scene shall we? Lets say there was a man who just lost his son to a vicious killer. It is time to go to the court of law and put the killer on trial for his crimes. We all wait to hear the judges ruling....and Shockingly the judge says to the killer. Well I forgive you, go free....what Justice has been done here? Is this judge righteous? Is this just? What would the father of the victim be feeling towards this judge? Respect? What would the people who have gathered to see this great day of justice be feeling towards this judge? Awe? Well why not? This judge had all the power in his hands, only a word from his mouth and the guilty was set free.let us even imagine the killer was repentant, let us imagine he looked to this father and gave his apologies, let us imagine the father forgave him the murder of his son. Should he be free without consequences? Will he learn from this and live to never kill again? Possibly, but probably not.
With The law of man, we have crime and punishment. With God's law we have sin and the punishment of sin, this is death. We have a Holy righteous God, a just God.
I will continue this in following posts, as I have met my limits here, Thankyou for baring with me, please allow me to give my complete thoughts and support before attacking me in parts, peace
