I did not “Just accept” the Christian upbringing I had, I questioned it, I was not the favorite in the family, and I could see hypocrisy . Even after coming to the conclusion that life was too complex, inter-related, and on so many levels that an "accidental occurrence " was not believable to me, the question still remained, how did one know which faith, if any or all ,was true? After filtering through enough other faiths to see the profound difference in Christianity, a difference not found anywhere else, I found I agreed with the Bible, that the evidence of God is in his creation that is all around us. be that the world and it’s nature, or the inhabitants and their nature. But there was a long time when I didn’t know that for sure. But, his spirit was in me and never left.
To me, the meaning of life is that very choice, The reason for life is to make a real choice possible, to acknowledge and accept, choose to belong to God, be a part of his family, or, to reject God, by refusing him, in what ever way one chooses to do that. As to why God would do it all this way, I have one simple answer, a personal answer I have not vetted as a biblical one fully, but it’s this.
God could create an endless supply of angel like worshipers, but as we all know, someone who chooses to love us and be with us, when they had significant and legitimate “other choices” has a special meaning, a special value. We can choose God, or not choose God, and there is an actual “other choice” we can choose, so it’s not like the choice is “really not a choice” . You could sum it up by saying we can choose to be our own God, deciding our own rules, morals, and values, or we can accept God as God and, with coming to know God, love God for his amazing and wonderful qualities, not the least of which is his own Love.
As for others, even those who reject or hate God. He tells me his instruction to me about them is to love them, as he does. I can hate evil, as God does, yes, but I am not free to hate a person because they do evil, even as I may be standing against that evil.
