Some manuscripts have the disciples worshipping Jesus. The textual support for this activity here is good. This is Luke"s first reference to the disciples worshipping Jesus. The Resurrection and Jesus" subsequent instruction made His deity beyond doubt for them. [source][source][source]
The disciples returned from the Mount of Olives to Jerusalem joyful because they finally understood and accepted God"s program for Messiah and for them (cf. Luke 2:10). Jerusalem would shortly become the birthplace of Christianity. Their constant praise in the temple, the place of prayer, was undoubtedly for the gospel, the good news that God has provided salvation for humankind through His Son (cf. Acts 2:46; Acts 3:1; Acts 5:42). Peter preached his sermon on the day of Pentecost10 days later ( Acts 2:1). [source][source][source]
"The return at the end of Luke to the mood of joyful praise of God that filled the birth stories rounds off the story of Jesus; it also affirms that the joy felt by the devoted Jews who greeted the infant Jesus has been justified by later events, bringing the story to a happy resolution. The joy and praise filling the disciples following Jesus" appearance and departure will continue in the life of the early church, as Acts 2:46-47 indicates." [1][source]
These original disciples set all of their subsequent fellow disciples a good example. We, too, should worship, rejoice, and praise God as we eagerly await the fulfillment of all that He has promised. [source][source][source]
