It is true of the complexity of the brain and so many organs of the human body in terms of things that can be achieved by themselves or through stimulation and it makes sense that man was created as a masterpiece, I mean that the human being is simple in terms of the things you need to be happy, and satisfied with yourself even when we ourselves think that we need many things, sooner or later we realize that with the simple was enough.
God owes nothing to the human being, but we owe everything to him, that makes me want to be at his service. However, like every father, he wants good things for us. Love for others does not reduce anyone but the opposite.
I understand that for you the bible does not have the same value that it has for me, it is your choice, but in it God has put a treasure and wishes that we all find it, I will not quote it but you can look for it if you wish, Proverbs 2 : 1-6
God will never take away our free will, it would be like having robots programmed only to always do what we want and not even human beings want that, when we create a robot we look for them to be as autonomous as possible, hence the artificial intelligence, etc.
Something is certain, to live in a land where peace and harmony reign, the human being must have certain qualities. Are we ready to live in paradise ?. The vast majority do not, but we can prepare ourselves as someone who is going to live in another country prepares. What I am going to say may seem contradictory but it is not, although I have the hope that God will fulfill his promises, I do not live my day to day counting on that I will be there, it is something that I would like with all my strength but That does not depend on me but on the mercy that God has for me, in turn that will depend on what God finds in my heart. Nobody can cheat him. Just be good? That is a good question.
As you say we are all free to believe what we want, I am not trying to convince you of what I decided to believe, I just thought that you felt regret for the uncertainty of the future and that is why I decided to tell you what God will do for the obedient humanity. Regards!
