Thanks for that post Dan, it is good to see some good Christian philosophy and teachings, i recognise it as the absolute truth because the same truths are also expounded in the Vedas
In the Vedas a soul empowered by God is called Avatar ( One who descends to earth ) to establish eternal principles.
There are of course many bogus cheaters who claim this but it is easy to identify the truth, just in the way Jesus stated in your qoute.
And also, a genuine Avatar will display miracles, and is also empowered to attract millions of devotees. Jesus fits these requirements in every way, there is no doubt he is the genuine article.
It should be made clear however that we are Gods only in the sense that we are part and parcel of God and not of course God himself.
If anyone claims to be God, just ask them to perform a miracle!
