If your leadership is  Christian you can openly reveal your failures. Leaders who are fully human do not hide their sins. Within you operates the principle of the cross, the modus operandi of strength and weakness.
This principle points up our problem -- we who are religious. We want a Christian reputation more than we want Christ. And yet our Lord, becoming sin for us, "Made himself of no reputation.". . .
Am I willing to hide my strengths and reveal my weaknesses? Are you? Telling our triumphs, our successes, our achievements, we glorify ourselves. . . 
Bragging about my goodness, I build barriers up; when I confess my sins, those barriers come down. Pagan outsiders get driven away by our pious parade of religious achievements. Building our high walls of intimidation, we make their friendly corner bartender look good. Christians are not half-angels with high-beam halos, but real live forgive sinners up close. . . 
Christ's death frees you from hiding your sins. You can be vulnerable and open. When you are weak then you are strong. You shake the darkness with irresistible blows: the divine might of weakness. You hit your hardest when your guard is down.
