...I'm kinda new to being a dedicated christian and I want to be more true to myself and god. I want to know what is considerd taboo and what will get me into hell that kind of thing...
Actually Bible promises eternal life for those who are righteous. And I have understood that righteousness is more than actions, it is like right understanding and attitude, which makes person do right actions.
These will go away into eternal punishment, but the righteous into eternal life.
Mat. 25:46
The condition for eternal life is not that we live according to some rule. It is possible to get into God’s kingdom, even if we have not obeyed God’s law perfectly, as you may notice from this:
"Don't think that I came to destroy the law or the prophets. I didn't come to destroy, but to fulfill. For most assuredly, I tell you, until heaven and earth pass away, not even one smallest letter or one tiny pen stroke shall in any way pass away from the law, until all things are accomplished. Whoever, therefore, shall break one of these least commandments, and teach others to do so, shall be called least in the Kingdom of Heaven; but whoever shall do and teach them shall be called great in the Kingdom of Heaven.
Mat. 5:17-19
Paul even said that everything is lawful for disciples of Jesus.
”All things are lawful for me," but not all things are expedient. "All things are lawful for me," but I will not be brought under the power of anything.
1 Corinthians 6:12
"All things are lawful for me," but not all things are profitable. "All things are lawful for me," but not all things build up."
1 Corinthians 10:23
But not all is good for us. So, if we think is something sin or wrong, I think it should be taught is it harmful. I have understood that if we reject God, it is sin and harmful. So I think it would be wise not to reject God in any situation. But things can be harmful also in physical way. So, to answer is something ok, I think you should think, is it harmful, if not, then it is not probably wrong or sin. If married couple does together something that they like, I think it could be ok, at least if it doesn’t cause harm and if persons doesn’t reject God. I think the same is with every possible action that people could do, if person doesn’t reject God and doesn’t do harm, I don’t think it is wrong. But obviously sometimes it may be difficult to see what is really harmful, especially if there is contradiction with what person wants and what he knows is good and right.
And lastly I want to remind, if we love God, we want to do his will.
For this is the love of God, that we keep his commandments. His commandments are not grievous.
1 John 5:3
And His will is according to the Bible in this:
Owe no one anything, except to love one another; for he who loves his neighbor has fulfilled the law. For the commandments, "You shall not commit adultery," "You shall not murder," "You shall not steal," "You shall not give false testimony," "You shall not covet," [TR adds "You shall not give false testimony,"] and whatever other commandments there are, are all summed up in this saying, namely, "You shall love your neighbor as yourself." Love doesn't harm a neighbor. Love therefore is the fulfillment of the law.
Romans 13:8-10
