Incidentally, the Grand Universe comprises of several local universes and the total number of living worlds is to the tune of about seven trillion!
To admit frankly, the Urantia Books' detailed information has helped me to transform from a near atheistic attitude to a firm believer of God and a sympathizer of all religions. It has also helped me to understand the predicament of Jesus Christ himself in managing the affairs of our own planet earth- a world full of free-willed mortals who are free to think and act even higher than himself. That too from a very insignificant and perhaps least developed world among his current domain of 3.8 Million worlds!
Being what Michael of Nebadon is, he would not in all probability like to interfere in the free-will capacity that has been so wisely bestowed upon all human beings just for the sake of inducing them to follow him!
For now, what most he would do is to give them some feeble advices in his own ways, that too for those who wish to listen ! Just as what he did when he lived here in the form of a normal human being named Jesus !
[Those who are skeptical of many planets and living worlds in our Milky Way Galaxy, I suggest them to read the latest estimates of NASA scientists which vindicates what the Urantia Book authors told us more than half a century ago. Read 'the Milky Way contains 100 billion planets' by MSN News. If you are curious to know what exactly the Urantia Book says about the actual numbers of planets which are abodes of mortals like us and more such information about our local universe Nebadon and its relation to the Milky Way Galaxy etc I suggest you read the Urantia Book Paper 32 para 2.9 onwards.
