Jesus wanted to upgrade the thinking of His time.
It is true that I too want to do the same.
As to converting others, when we reach heaven God does not care which God we follow as long as our hearts are good. Whatever that means to each of us.
None are refused regardless of our moral condition at death.
I can only do what I think my duty to God and my fellow man dictates.
I can only express my God's ideas of morality. If they are the same for the reader then I do not care what he call his God. It is the philosophy that is important, not the name of God.
If one must lie to express his God then I would think that their God is weird. Like fundamentals who believe in talking snakes. If it takes such to express their God then those intelligent enough to reject this impossibility are right in looking elsewhere for God.
