In the sermon **“Great Day in the Mourning,”** based on John 16:16–24, Pastor Chris explores how Jesus transforms grief into lasting joy through the presence of the Holy Spirit, the “Spirit of Truth.” As Jesus prepared His disciples for the sorrow of His departure, He promised that their mourning would turn to joy—a joy rooted not in changing circumstances but in divine truth and relationship with God. True Christian joy, unlike worldly happiness, coexists with pain and hardship because it flows from the Spirit’s work within us. By facing pain honestly, choosing to see Jesus in our suffering, and praying in His name with humility and confidence, believers experience the deep, unshakable joy that only Christ can give—a joy that begins now and will be made complete in eternity.
