James, youn didn't really expect to get an answer, did you? Although they claim they "know" the mind of God, when asked why God did something they tell you "for his desired Holy direction" which, translated into plain English, reads just because.
There isn't one. It's a clear moral contradiction that cannot be resolved.
Although I cannot speak for many of the posters here, whose view of Christianity is far from the mainstream...
Christians do not (if they know their Bible) claim to know the mind of God.
Isaiah 55:8
“For my thoughts are not your thoughts,
neither are your ways my ways,”
declares the LORD.
9 “As the heavens are higher than the earth,
so are my ways higher than your ways
and my thoughts than your thoughts.
