Also, even though I am not really a religious person, I find it odd that in 100 comments, no one has mentioned the Bible (or any holy book that I could see). So, given that I have read it, and that it was inspiring in many ways, here you go:

The Bible


- Jason Slover, just someone in a forum discussion about books that inspired you. 
( many people see the bible only as a moral guidance, inspiring books, but miss out the divinity aspect of it)

Now, the gospel brings us a new freedom from lying. How? We don't overcome lying by simply saying to ourselves, "stop lying!" Rather, we ask, why do I lie? What leads me to do it? And the answer is always that something that we delight in (i.e. worship or rely on for our worth) more than God is threatened. And so we lie. But how do we change? We cannot "just say no". The most effective way of withdrawing the heart from one object is not by turning it away upon desolate and unpeopled vacancy, but by presenting to its regard another object more alluring still.

Thomas Calmers - Expulsive power of new affection

It is equally true that adoption lays on one the abiding obligation to keep the law, as the means of pleasing one's newfound Father. Adoption puts law-keeping on a new footing: as children of God, we acknowledge the law's authority as a rule for our lives, because we know that this is what our Father wants. The sins of God's children do not destroy their justification or nullify their adoption, but they mar the children's fellowship with their father.
