Since that is how far back that book goes it is the same Abraham so it has to be the same God that is worshiped. It looks like it should have been the guide to the nations in OT times. The timing of it coming out was after the RCC went off the rails by altering the books they had and they invented their own bible so perhaps this was god's was of giving people an alternative than the corrupt RCC which was 'the Church' at that time.
God did the same things two times in the Bible. When the fallen angels got out of hand they were put into the Pit. When Israel went off the rails God had Neb come in and removed them from the land and Daniel and a few others did okay and there were many who returned to Israel 70 years later,well okay a few as many would have died from old age.
One thing is sure the tolerance that Christian are told to exercise is gone and it has been since about 400AD. The verse below even states they would be given the truth (Hebrew for the OT and Greek for the NT) and they would mess it up. These verses cover Rome's whole 500 year rule over Jerusalem.
Da:8:8-12:
Therefore the he goat waxed very great:
and when he was strong,
the great horn was broken;
and for it came up four notable ones toward the four winds of heaven.
And out of one of them came forth a little horn,
which waxed exceeding great,
toward the south,
and toward the east,
and toward the pleasant land.
And it waxed great,
even to the host of heaven;
and it cast down some of the host and of the stars to the ground,
and stamped upon them.
Yea,
he magnified himself even to the prince of the host,
and by him the daily sacrifice was taken away,
and the place of his sanctuary was cast down.
And an host was given him against the daily sacrifice by reason of transgression,
and it cast down the truth to the ground;
and it practised,
and prospered.
