well, like I already mentioned, since most of Jesus' parables are about faith it would be kind of difficult to exclude this one from any mention of it. And I already mentioned it above.

Man does not live by bread alone.

If you sin and continue to sin, with or without asking forgiveness, my guess is that you never had salvation to begin with. The holy spirit perfects us, we are his work... and sin is the main business. If he isn't working on you to convict you of your sin, I would question why you think you are saved.

I am not sure eating ham enters the equation in any large way but murder and deceit would. Not eating pork is just one of the minor ordinances to keep you and healthy and give you longevity etc, it's not a major commandment.
