Grace is to be let into a place that you don't have a right to be.
How do you change your behavior? Change what you worship
Pride is the carbon-monoxide of Sin. It silently and slowly kills you without you even knowing.
You can't live the Christian life without a band of Christian friends, without a family of believers in which you find a place.
If you need something in addition to God to make you happy, that is your true King.
It's important to remember the Gospel is a story; not a set of bullet points.
