This is a big reason why I don't concern myself with whether my actions are "heaven" appropriate, different people consider different things sinful. Not even the bible could be a definitive source for what will is and is not sin as extremists will say that things like masterbation and men with long hair are sinful, drugs and alcohol and sex are sinful etc.
I lie when it takes too much effort to tell the truth, unless the matter at hand is important, I do a lot of drugs, I masterbate frequently, I swear and by my standards all of this is perfectly acceptable. If you think about it, these things really don't harm anybody so why should I be thrown in hell for them?
Life isn't permanent.
