They replaced Judas, the traitor with a vote and then waited in an upper room for the Holy Spirit to come as Jesus promised. There is no record of any fear in them as when Jesus was crucified, (John 20.19)
After Jesus Ascended back to heaven the disciples then followed the command of Jesus , and went to all the world to make disciples. Peter went to Rome ad Thomas came to India.
It was the angels.
his disciples, before Jesus ascended into heaven
The ascension implies Jesus' humanity being taken into Heaven. The eleven disciples were there except Judas
When Jesus was on this earth, with his twelve disciples , Jesus was filled with the holy spirit, but once he was crucified and had ascended into heaven, he was no longer with them in person. But he had promised to sed the holy ghost as a comforter to them, asnd they were filledwith it on the day of Pentecost.
Jesus told his disciples to go and spread his name and his word. After saying that he gave the disciples the language of tongues.then Jesus ascended towards heaven.
John 3:13New King James Version (NKJV) 13 No one has ascended to heaven but He who came down from heaven, that is, the Son of Man who is in heaven.[a]
Jesus' disciples
The Acts of the Apostles describes what they did after Jesus ascended to heaven. They were then Apostles as witnesses to all that Jesus said and did, especially the resurrection. At this time disciples was also used as the name for all the Christian believers since they were all devoted followers of Jesus (no unbelieving nominalism then). Prior to Acts, the four Gospels, although centered on Jesus, record much of what the disciples (as they were then called) did and said.
Main goal is to spread the gospel. Jesus told His disciples to 'go into all the world and make disciples'. For a person to become a disciple of Jesus Christ they must first respond positively to the gospel.
They all faithly remained Jesus disciples after his death.
The Ascension of Jesus Christ takes place many days after His ressurection, or 'Easter'. According to the Bible He was seen by many people, including His disciples during the 40 days after His ressurection. At the end of the 40 days He ascended to Heaven in full view of the disciples.
The Long Ending* of Mark's Gospel says that Jesus met the disciples at a meal in Jerusalem and, after talking to them, ascended to heaven.Luke's Gospel says that Jesus led the disciples out on the road to to Bethany, where he ascended bodily to heaven, the same evening as his resurrection.Acts of the Apostles, although by the same author as Luke's Gospel, says that Jesus appeared on earth for forty days, providing many proofs that he was risen. He then told the disciples not to leave Jerusalem, and ascended bodily to heaven. This would appear to have been in a room in Jerusalem.Footnote*The Long Ending does not exist in the earliest manuscripts of Mark's Gospel, but was added much later, to more or less harmonise Mark with Matthew and Luke. There was also, at one stage, a "Short Ending".
