And if God's intent was to create beings that would freely choose to show him love, then every time someone chooses the opposite would be a failure on God's part.
Your word choice suggests you agree with me: what would we need "rescuing" from if God's creation - and therefore God as a creator - had not failed?
There are many parents who have more than one child and sometimes some are loving and some are not.
I met a man at a campsite and noticed how well behaved his children were and mentioned that to him.
His reply startled me because he said he also had a son in jail.
Did that make him a failure as a father ___________
We see in Scripture that God had two (2) Son/son's. One turned out well, one did not.
Jesus proved to be the Son who turned out well, and Satan proved to be the son who did not turn out well.
Jesus did Not prove their Father to be a failure.
Jesus will vindicate his Father and his Father's name will be hallowed - John 17:6; John 17:26
