1 Samuel 17:33 (KJV) And Saul said to David, Thou art not able to go against this Philistine to fight with him: for thou art but a youth, and he a man of war from his youth.
In any venture of faith there may be those who speak words of discouragement. What Saul did not realize was that David was trusting God for victory, not himself.
God calls people of all ages at all seasons in life to pick up their cross and follow Him. We each have a precious testimony to share with non-believers, and our stories begin at different ages. We unintentionally view younger pastors and teachers as inexperienced or immature in their faith. We must remember that once someone has surrendered their lives to the Lord, the Holy Spirit will begin to guide their steps. We are responsible for spiritually mentoring young leaders and helping them flourish in their relationship with the Lord.
