Ya, we always find some form of justification if we want to. You
will always find some people to agree with you certain things are
ok, certain things are not. But ultimately, as a christian, you
look to God's word and ask yourself if it is the wisest thing to
spend your money.
Having said that, you mentioned you are in financial difficulty,
are you currently employed? You may want to speak privately to
someone here about your situation, we may be able to offer some
advice.
