I get your perspective on this and have some agreements as well as some disagreements with it.

I know the lazy people you are referring to, I lived with one where they would commit sins and then drop to their knees to pray for forgiveness and then do the same shit. I think in this regard I do have a lot of issue with it however it does also have something many others don’t: personal choice.
We are given the opportunity to learn a lesson and I think that’s important. We can choose to learn the lesson of not being a glutton and eating all the food while not saving it for others. We are given the choice to not partake in the deadly sins but some of the most important lessons we have to learn on our own and make our own decisions for. It’s not good to be dictated to for a lot of things which is where some other religions like Islam run into problems. We need the freedom to choose for ourselves and I think this is where Christianity has a big benefit.
