So yes I understand that Lust is Very strong sexual desire.
But I am confused as too what exactly that means, I mean say if you are walking down the street and you see a woman and think she has a beautiful body or breasts etc, and just leave it like that just noticing that she is physically beautiful and then just move on is that classified as Lust? Or is it Lust for you even looking at her body or breasts in the first place?
I am just slightly confused with this as this usually happens to me I notice a woman and look at her body and think she looks beautiful and then I move on without wanting to have any further connection with that woman, is that lust for looking at a womans physical beauty?
Also this is a problem I have sometimes where I could be talking to someone or just thinking to myself when suddenly I get a lustful image or thought come into my head which I did not want, as soon as it appears I expel it straight away, is that lust, I did not want the image in my head in the first place so is that a sin either as I suppose it wasn't with full consent. I must add that in the first place the thing I was talking about or thinking about is not related to anything sexual or anything sometimes these thoughts or images pop into my head.
The point is if anyone could answer me as to whether the two things I have described are actually lust it would be greatly appreciated, and if any one could give me a clear definition of what Lust is without so much terminology it would greatly help me as at the moment I am stressing if I have committed Lust under these two actions.
