The disciples saw Him perform miracles.
The disciples saw Him crucified.
The disciples saw Him rise from the dead.
The disciples saw Him ascend into Heaven.

And what happened next?

They all joined together constantly in prayer, along with the women and Mary the mother of Jesus, and with his brothers. Acts 1:14

They didn’t start planning.
They didn’t brainstorm.
They didn’t go to work.

They prayed.

The first thing they did was pray.

Prayer preceded three thousand people coming to know Christ in one day.
Prayer preceded the greatest movement that the earth has ever seen.
Prayer preceded the message that over one billion people around the world embrace today.

Simply stated:

Prayer preceded the power.

Don’t you think you and I should give it a try?
