In You Can Change, Tim Chester mentions four life-changing truths about God. I don't think it's an overstatement to say that every act of sin flows out of a failure to grasp one of these truths in the moment of temptation:
1. God is great - so we do not have to be in control.
2. God is glorious - so we do not have to fear others.
3. God is good - so we do not have to look elsewhere.
4. God is gracious - so we do not have to prove ourselves.
Get these four truths deeply rooted in your heart, friends. They are fundamental weapons in the war against sin.
