Following Jesus requires courage that comes from beyond this world - courage rooted in our eternal home in heaven. While the Christian path involves suffering and sacrifice, understanding heaven as a real, physical world where God dwells with us provides the strength we need. Heaven isn't just the absence of pain, but God's tangible presence filling everything. This future reality gives us courage to endure present suffering and release our grip on earthly things. When we truly believe heaven is our citizenship, we can face difficulties with hope and live generously, knowing we possess something far better that lasts forever.
