Jesus told His disciples to wait.
Acts 1:4-5 (NIV)
“Do not leave Jerusalem, but wait for the gift my Father promised, which you have heard me speak about. For John baptized with water, but in a few days you will be baptized with the Holy Spirit.”
The instructions were short on details. I don’t think they knew what to expect. Nevertheless, they waited.
It still happens that way. We wait on God, not sure what’s next.
Here I am, Lord, waiting. Go ahead, surprise me.
