I've been reading for a while and all I can say is that:
1. This is a debate that would be difficult to resolve because all the different factions are coming into it from different perspectives. And until you have the same basis, you cannot understand each other.
2. The Christians that have argued for Jesus being God, have done an excellent job.
3. To understand where God the Father was when Jesus died on the cross can only be understood, if you see God as omnipresent, He is not confined by space.
4. To my fellow Christian brothers and sisters, in trying to explain this concept to the others, let us desist from insult or condescending statements. Let's follow the words of Apostle Paul, who exhorted us not to involve ourselves in foolish arguments. After a while, discussions can turn into foolish arguments that could get personal, I beleive that is when we should take a step back
