In Acts 1:6–11, we see Jesus’ followers still learning what it means to live on mission — not by their own strength, but by the Spirit’s power. This sermon calls the church to move from watching to witnessing, from waiting idly to living faithfully. The promise of Christ’s return isn’t a reason to stand still; it’s a call to rise up, depend on the Spirit, and live with urgency, hope, and purpose until He comes again.
