I don't post here wrongly believing that anyone cares what I believe. Of course Psalm 139 is not talking about despising babies. David and God did not mean that passage to suggest they despise babies. That passage means David and God despised those that despised God.Who cares what you believe?
Make an argument or find a different hobby.
Psalms 139 is talking about a babies development inside the womb and says nothing at all about God unjustly despising unborn babies.
