What does acknowledging God have to do with reality? I don't mean this sarcastically, but do you know what reality is?What does telling them have to do with reality?
By "taking on", I assume you mean have our sin attributed or ascribed to him. I don't believe God punishes anyone for what another person does. Especially not his own Son. I believe Jesus "took the sin" of mankind by having them inflicted on him. In other words, what was done to him by people was sinful.I believe Jesus chose to do the will of the father that resulted in Him taking on the sin of the world.
Well, if God is telling you to do something, then you should do it. I'm sure God will never tell me to join any group which requires me not to proclaim him.We are not to entangle ourselves with the unclean things of this world but this doesn't mean we are not still in this world. To separate completely we would need to be dead. God's wisdom can help any situation no matter the topic.
And while it's nice when people agree, I don't base my faith on how many people agree with me.
