The gospel accounts end with Jesus saying "Go!". Acts opens with Jesus saying "Wait!".
The "Go" of the Great Commission is very familiar to us (Matthew 28: 16-20), but are we aware that Jesus also told His disciples to "wait" (Acts 1:1-11)? Jesus said, in effect, "Don't go anywhere, don't do anything, until you receive direction from The Holy Spirit". Then God moved in a powerful way.
"Therefore, go and make disciples of all the nations, baptizing them in the name of the Father and the Son and the Holy Spirit. Teach these new disciples to obey all of the commands I have given you. And be sure of this: I am with you always, even to the end of the age." -- Matthew 28:19-20
Once when He (Jesus) was eating with them, He commanded them, "Do not leave Jerusalem until the Father sends you the gift He promised, as I told you before. John baptized with water, but in just a few days you will be baptized with the Holy Spirit" - Acts 1:4-5
Watch God Work!
On the day of the Pentecost all the believers were meeting together in one place.
Peter gives the invitation:
"So let everyone in Israel know for certain that God has made this Jesus, whom you crucified, to be both Lord and Messiah!"
Peter's words pierced their hearts, and they said to him and to the other apostles, "Brothers, what should we do?" Peter replied, "Each of you must repent of your sins and turn to God, and be baptized in the name of Jesus Christ for the forgiveness of your sins. Then you will receive the gift of the Holy Spirit. This promise is to you, to your children, and to those far away -- all who have been called by the Lord our God." Then Peter continued preaching for a long time, strongly urging all his listeners, "Save yourself from this crooked generation!"
Those who believed what Peter said were baptized and added to the church that day - about 3,000 in all. All of the believers devoted themselves to the apostles' teaching, and to fellowship, and to sharing in meals (including the Lord's Supper, and to prayer). - Acts 2: 1, 36-42
There are plenty of Easter devotionals that help us reflect on the gravity of the cross and the glory of the resurrection. But what do we do after Easter? The risen Jesus didn't leave in a hurry: He visited with His disciples over a 40 day span, putting the finishing touches on three years of training. He wants to do the same with us. Spend time with Jesus, go and make disciples (spend time with others), then wait on the direction of the Holy Spirit and watch God work!
