Bounce back after you are knocked down
In Matthew 16, Peter was both a "rock" and a "stumbling block." He was both blessed and disgraced almost in the same breath. It is enough to discourage any leader. You are the foundation. You are the devil's advocate. Discouraged by the disapproval of Jesus, yet blessed by the warmth and affection of Jesus. Resilience may be the cornerstone of effective leadership. Peter denied Christ 3 times yet went on to become one of the leaders of the early church.
"Those who accepted his (Peter's) message were baptized, and about three thousand were added to their number that day." - Acts 2:41
