A question about purity for Christians?

You know how far "pure" is. You're just looking for permission to not do what you promised yourself and God you would do. I do that a lot with exercise. I can come up with all kinds of reasons why I don't have to or don't have time or need to wait....The bottom line is, they're excuses. I'm not going to give you permission to go back on your promise. I know what it feels like when I've promised I'd exercise and then give into excuses. It's not good.
