The Bible is the best and most important tool in discerning direction from God.
Failure is an event, not a person. You are NOT a failure!
Don't worry when you're being persecuted for God, worry when you're not.
With prayer, you may be able to start one discipline or habit that will overflow into many more positive, God-honoring traits.
Good can be the enemy of great.
God could have programmed us as robots to do whatever he tells us, but then we'd never have the freedom to love and worship him.
