The Immorality of God - Slavery in the Old Testament

[Angrboda]

So, taking them where they were at as product of "the times" in which they were living, God began to reveal a progressive message that was open to rejection. 

He went slowly, taking a thousand years and more, giving them as much as they could handle, punishing them when they disobeyed, rewarding them when they were obedient, until they were ready to receive the fullness of His message, the Word, the incarnate Son of God, Jesus Christ.

Would you like some paper on which to write your bible?

What God revealed to them either was not moral because today we have the 'correct' moral view on such things, according to your timeless god. Or, what god revealed to them was moral, and those Christians who oppose slavery are immoral, according to your timeless god. Which is it?
