Joy That Grows Up explores what joyful Christian maturity looks like when it’s lived out together in real community. In Philippians 2:1–18, Paul shows that true joy isn’t found in self-promotion or spiritual burnout, but in gospel-shaped unity, Christlike humility, and obedient living empowered by God. As we learn to share the mind of Christ and “work out” our salvation together, we discover a deeper, more resilient joy—one that grows as we serve one another, watch our attitudes, and trust God to supply both the desire and the strength to obey.
