I see people think they’re outsmarting religion and creating loopholes in their faith by switching over from “being religious” to “having a personal relationship with God”. They hand-craft their own moral code and argue with anyone that tells them they’re defying God’s laws by saying “My relationship with God is my own; it’s not your place to judge it.” This is nonsense.
If your personal relationship with God is based on the Bible, then every time you choose to ignore a part of the Bible, you are a hypocrite. For your basis of faith to be this book, if you choose the parts you like and reject the parts you don’t like, you are creating a Frankenstein’s Monster of a faith that is solely your own. You can’t believe that THIS is the one true god while claiming parts of the text that your faith is based on are false.
If you want to believe there’s a greater being, not necessarily the God of the Bible but some other god, and imprint upon him your values of what you think is true and just, well… if you want to create your own Build-A-Deity, that’s your prerogative. But don’t call yourself Christian.
Sins are laid out in the Bible. It also lays out that all of God’s children are inherently sinners who can only be saved by the grace of God and Jesus Christ. You cannot choose to sin while knowing that it is a sin, planning to later ask for forgiveness for your knowing and willing sin, and think that this is done in a just and loving relationship. That’s hollow. You don’t want forgiveness; you want to do whatever you like and then exploit “Jesus’s love” to save you. If any of this is true, God SHOULD turn his back on you. You don’t love him; you’re exploiting him.
If you believe that there is an all-knowing and all-powerful god who has created everything and all of his rules are final, you cannot reject any of those rules and stay honest to yourself and to your faith.
For me, personally, the more I read the Bible, the less it made sense and the more I disagreed with it, its teachings, and its god’s commandments, so I’m not a Christian. I don’t have any faith in any religious text or believe in any deity. I also don’t consider myself an atheist because that’s a loaded label; people will assume all sorts of things about you if you call yourself an atheist, and that’s just not a fight I care to take on. (I already have to deal with being an anarchist. One label fight is enough for me.) Modern atheism would be better labeled antitheism; most atheists are staunchly opposed to any possible spirituality, and I’m not necessarily, I just have yet to see any evidence.
So I really don’t care whether you do or don’t believe in the Bible. What I do care about is that you be consistent and honest with yourself and your beliefs. If you cast off part of your god, how can you not cast off the entire thing? You are only imagining a customized god.
