Read Acts 1:6-9

[Jesus] said to them: “It is not for you to know the times or dates the Father has set by his own authority. But you will receive power when the Holy Spirit comes on you; and you will be my witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth.” – Acts 1:7-8 (NIV)

The time in the upper room was like a retreat. It gave the disciples time to reflect on what Jesus had been teaching them the past 3 years, and allowed God to root out the last vestiges of their old ways of thinking, acting and planning. Until this was done, they weren’t ready to move into the mission Christ had given them, to spread the gospel to the whole world.
Many of you are not new in the faith; you too have been with Jesus, some for many years. How can you take a time of retreat this week and give God the time to prepare you for your next part in God’s mission?
