Suffering from "Truth" decay? Brush up on your Bible!
A spiritual diet of processed theology, sweetened doctrine, and sugary platitudes consisting of "Trendy Fail-Proof Psychobabble" will slowly erode "the teeth" of biblical Christianity. When you find yourself drifting from your values and you need to enrich your spirituality, reach out to God through the Bible, attending church and through prayer. He will lead you back to your true spirit.
And you will know the truth, and the truth will set you free.
