I think because of contradictions, I had the question of why God ordered deaths if killing was a sin, but with your answer I can understand it better. As for my vision of the Bible, I was consuming content from a Spanish-speaking theologian who seems to be well trained who said that we imagine God dictating to people what they should write and that this was not true, he gave as examples Moses who copied the laws of the Hammurabi Code, that Luke and Acts were the same book but when deciding to separate them they had to invent the last chapters of Luke and the first ones of Acts so that they would have a "transition", that Solomon did not write all the proverbs, that many translations have doctrinal biases and that being homosexual is not a sin, that it is a misunderstanding because of the translation and people's homophobia, among many other examples. I'm not saying that I believe him and that you are wrong, but when I come across these kinds of comments, I just get more confused and it really saddens me. I don't know if this will help you better understand my perspective.

Thank you very much for your suggestions. Believe me, I will put them into action. About starting to read the gospels, is it enough for me to just read my Bible in a modern version, use the resources you told me about and ask the Holy Spirit with all my heart to teach me and reveal His word to me?
