Another subtle form of justification is to accept a lower standard for ourselves than the one revealed in scripture and through modern prophets. Alan Medinger counsels us to be on guard against "the attitude that says, 'God, I am doing the best I can do; this is just the way I am.' Rather than working towards the gospel standard, we adopt a tolerant, indulgent attitude that declares, 'If I only go off on a sexual binge once a year, I'm better off than I used to be. Besides, God understands my weakness.' I have known people who for years have justified their ongoing sin as being reasonable, given their emotional and psychological makeup." It is subtly arrogant to assume that our understanding of ourselves exceeds what God has revealed in scripture and through his prophets.

I've been perplexed myself as I read various accounts of how people are dealing with their struggles when they say something to the effect that they've done the best they can and that's good enough (and so now I'm going to move on and be gay and God must be okay with that). I mean, that's a legitimate worldview and everything, but I don't see it as compatible with LDS doctrine.
But on the other hand, there's some hand waving in the doctrine when you talk about the atonement covering our imperfections "after all we can do". "Can" meaning what? Can we be perfect? Theoretically there's nothing keeping me from living a sinless life. If it means after a legitimate and persistent effort, that's another story. So, do we have to be free from big sins like immorality but not worry about other sins?
Maybe it's a matter of our attitudes. If a person is failing on a regular basis to abstain from his sexual weaknesses, but humbly strives to do better, he's in a different situation than one who excuses himself altogether for one reason or another. I dunno...
