What do you want to be when you grow up? It’s a question that never really goes away. Beneath it is a deeper longing: Does my life matter? Do I have a purpose? Looking at the life of David, we discover that God’s greatest calling isn’t tied to a career, title, or stage of life—it’s tied to the Holy Spirit working through us. The same Spirit who empowered David and Jesus has been given to every believer, enabling us to live with purpose, impact others, and fulfill God’s calling. Even when we’ve drifted, failed, or settled for comfort, God invites us to rekindle the Spirit’s work in our lives and step into the purpose He created us for.
