The two cardinal sins of leadership:
1.) Mistaking giftedness for spiritual maturity. Many young leaders are thrust into positions of leadership way too early in their Christian walk because of their evident giftedness. But spiritual giftedness is not the same as spiritual maturity. Gifts are received; maturity is something you grow into over a period of time.
2.) Mistaking fruitfulness for holiness. Successful ministry is not measured by numeric indicators. When Christ addressed the seven churches in Revelation, he did not commend the larger churches and rebuke the smaller ones. Instead, he hit at the heart of character, faith, endurance, compromise, idolatry, and immorality.
