Jesus had arranged to meet the disciples in Galilee after his resurrectionThe rising of Christ from the dead, three days after the crucifixion..
They went to a high mountain and worshiped him, although Matthew notes that some doubted.
Jesus gives them some instructions and reassurance, this event has become known as the Great Commission.
Jesus tells the disciples to:
“Go and make disciples of all nations, baptising them in the name of the Father and of the Son and of the Holy Spirit, and teaching them to obey everything that I have commanded you.”
The disciples began their missionary work in spreading the good news about Jesus and obeying his instructions from the Great Commission.
Christians are also called to follow these instructions as disciples of Jesus. Some people do this by:
carrying out missionary work across the globe
giving themselves to religious life (perhaps by becoming a priest or a minister)
living a Christian life as an example to others
Jesus leaves the disciples with an important fact:
“remember, I am with you always, to the end of the age.
This would have given them confidence and reassurance when they were completing their difficult mission.
