Sometimes we’re over eager to serve God in what we do. In my twenties with Youth for Christ, I mistook my youthful enthusiasm and zeal for the authority and strength of God. Six months of physical exhaustion followed at age 27. A hard lesson taught me by God. However, Jeremiah humbly responds, acknowledging concerns about his youthfulness. God encourages him, for when God calls it is neither age nor experience that counts, but the seal of God’s approval.
