Yes, there is such a thing as sin, although God does not put sin on levels, sinning is sinning everybody will face the Judgement of God. Sin; lying, committing adultery, stealing, disrespecting your mother and father, every body falls short of the glory of God. But God has sent his only begotten son to die on the cross for our sins, so that we don't have too.
Sin
The thing that you can do is a unforgivable sin is cursing the Holy Spirit.
Sin
There is no such thing as a little sin. God said if you hate your brother (or anyone) then that is just like murder.
I am unclear as to what the "reality of sin" is. Sin itself is a very real thing in almost every religion. The real questions what are: what forms does the sin take, what categories of sins are there, how do you commit sin, how do you repent from sin, what are the physical/social/psychological effects of sinning, etc.
It's not a sin. It's a good thing. Not going, however, it's a sin.
I am fairly sure that 'sin;' just means 'sign'. The whole thing means, go back from the sign, to the end of the piece.
Yes. Everyone will have sin in their life - Jesus was said to be the only being on this Earth who lived without sin. If you believe in that sort of thing, of course.
by trying not to sin do the wrong thing obey the 10 commandments
God loves everyone but hates sin, if you don't believe me, the Bible will tell you the same thing.
I imagine that it would be a sin depending on several things: how you presented it (as a sin or as a good thing), how graphic you were in your description, etc. The best thing to do would be to submit a draft of this to your confessor or a priest that you trust and have them critique it. If you are writing totitillateor shock, thus giving scandal, then this would be a serious sin and you should not even consider that.
Yes, he forgives you for every thing
