If you’ve decided that the Bible isn’t enough for you, that perhaps it is merely one piece of a bigger spiritual puzzle, then you are stating that you no longer believe that God and God alone is the source of your salvation.
Just be aware of the decision you are making when you set aside God’s word in favor of the teachings of another prophet, philosopher or sophist.
You deny the finished work of Christ, you deny the sufficiency and authority of God, and you make yourself the arbiter of “truth.” And, while that’s certainly a great job for anyone to have, I’m sorry to say that the position has already been filled.
It’s a simple reality, really: You create the Universe, you get to make the rules. So, until you can manage the former, don’t presume to attempt the latter.
