Jesus said he is the perfect representation of the father, he said, when you have seen him you have seen the Father, I and the Father are one.
Why does Jesus say,”you have heard men of old say. . . this and that, but I say. . . something completely different”. Jesus said “love your enemy”, how is it then that men were being obedient to God by slaughtering men, women and children, then going on to steal their possessions. Did God really kill the first born in Egypt, drown whole people groups?
I can not see God the son killing babies like God the Father did in the OT, they are not one.
I too am excited by progressive revelation, but you are absolutely right, it’s not really a limitation on God but more on our ability to understand him.
When we look at the “god” of the old testament, we see a god fashioned in man’s own violent image. And as we continue to look through history, we continue to see that pattern – even to today’s capitalist judge who American Evangelicals call “God”.
I think progressive revelation is more or less the progression of humanity as a whole toward the example of Christ.
