its not that it "feels good...don't do it"
its more like "if it can seperate your relation with god, don't do it"
"if it fills your life, don't do it"
temptation pretty much, and giving into temptation can be risky
but you won't burn in hell
you'll only really burn in hell if you turn your back on jesus
(thats the simplifide version of it)
"Love is patient, love is kind. It does not envy, it does not boast, it is not proud.
It is not rude, it is not self-seeking, it is not easily angered, it keeps no record of wrongs.
Love does not delight in evil but rejoices with the truth.
It always protects, always trusts, always hopes, always perseveres.
Love never fails. "
-1 Corinthians 13:4-8
