Why are you (still) a Christian?

[LinuxGal]

Isaiah represents the final state of Hebrew theology (monotheism) while the sin of idolatry remaining on the books points to the henotheism of the earlier centuries.  Worshiping another god when Yahweh was the only god makes as much sense as a man and woman alone on a deserted island worrying about adultery.

I don't think that holds any water because henotheism seems to be the theological consensus from Genesis through Revelation.

True, Isaiah's monotheism doesn't hold water:

OT:

Exodus 12:12 For I will pass through the land of Egypt this night, and will smite all the firstborn in the land of Egypt, both man and beast; and against all the gods of Egypt I will execute judgment: I am the LORD.

NT:

2 Cor. 4:4 In whom the god of this world hath blinded the minds of them which believe not, lest the light of the glorious gospel of Christ, who is the image of God, should shine unto them.
