It is more dangerous to be successful in ministry than to be a failure. People will forgive failure much quicker than they will forgive success. Success makes you a target of the enemy. Failure means you have already been shot down and no longer remain a threat. There is no longer a need for the enemy to target you.
Resistance, attacks, and opposition are signs that you are on the path to spiritual success.
“If you aren't in a head-on collision with the Devil, it's because you are both headed in the same direction.” --Mike Signorelli
