The Ascension of Jesus (Acts 1:1-11)

What is the main thing Christians are to be getting on with while we wait for Jesus' return, and do we have everything we need to do it?

1. We have a kingdom to proclaim (vv1-3)
2. We have a Spirit to cleanse (vv4-5)
3. We have a Spirit to empower (vv6-8)
4. We have a return to await (vv9-11)
