The eleven disciples went to Galilee, to the mountain to which Jesus had ordered them. When they saw him, they worshiped, but they doubted. Then Jesus approached and said to them, "All power in heaven and on earth has been given to me. Go, therefore, and make disciples of all nations, baptizing them in the name of the Father, and of the Son, and of the holy Spirit, teaching them to observe all that I have commanded you. And behold, I am with you always, until the end of the age." (Mt 28:16-20)
The disciples went back to Galilee. As the disciples started their journey from Galilee to Jerusalem so now they start their journey again (after resurrection) from Galilee. This is to show that one has to start one’s journey from his own place of origin. He has to start from his place of origin and journey towards Jerusalem. Everyone has got his own Galilee and everyone has to begin his journey from there.
They met Jesus on a mountain. Mountain is the place where God dwells. Mountain is the place of revelation (Sinai, Tabor, Zion etc). After resurrection Jesus revealed himself to the disciples on a mountain. The disciples also worshiped him. Jesus was accepted as God and worshiped on a mountain.
Jesus affirms his Godhead (all power in heaven and on earth has been given to me); commissions them (go therefore and make disciples) to baptize them and teach them; and assures them of his continual presence till the end of days. He takes the role of god among his people. After resurrection Jesus takes the role of God and fulfils it among his disciples.
