Boldness is behavior born out of belief.
Failure is an event, not a person. You are NOT a failure!
Be careful not to blame yourself if someone rejects Christ. If you do, you might be tempted to take credit when someone accepts him.
Those who have it stick with what brings it.
You can have control. You can have growth. But, you can't have both.
Don't insult God with safe living and small thinking.
