They was bummed and sad but then they started christianity.
In Luke's Gospel, Jesus went to heaven on the evening following his resurrection. In Acts of the Apostles, Jesus went to heaven forty days after his resurrection. In neither case, does it state where Thomas went.
They went to all parts of the world to spread the word of God.
Jesus was resurrected (raised from the dead and in Heaven) when Christianity began. Christianity began with Jewish apostles who believed that Jesus was the Messiah.
Jesus had 12 apostles.
Jesus gave His apostles the authority, to preach all around the world. Jesus did this by sending them the Holy Spirit. After Jesus' death, the apostles were afraid to be killed, so they stayed in a small home. One day the Holy Spirit appeared in the form of tongues on fire. After this, all twelve apostles, could speak in different languages. This was so that they could preach the word of God to all Nations of the World.
Jesus remained on the Earth for 40 days after His resurrection. He then ascended into Heaven. Ten days later, on Pentecost, the Holy Spirit came upon the Apostles and after repentence, upon those who were gathered there.
Jesus passed the bread to the Apostles sitting close to him, who inturn passed to the other Apostles.
The Apostles were not paid. They spent their lives following Jesus around for no pay.
According to the Gospel account of Luke (Luke 24:44-53), Jesus told the Apostles to preach the good news and then blessed them before being taken into heaven. According to the Gospel account of Mark (Mark 16:14-20) Jesus appeared to the Apostles whilst they were eating. He told them to preach the good news to the whole world, and was then "..taken up into heaven."
Two events that form teh backdrop for the Acts of the Apostles are the ascension of Christ into heaven, and the Day of Pentecost, in which the apostles were given the Holy Ghost to aid in their work. The idea was that Christ, though absent, was still directing their work from heaven through his Holy Spirit.
There are several instances of Jesus leaving the Apostles. For example, after the Last Supper, and after the Apostles fall asleep, Jesus leaves them to go apart in the Garden of Gethsemne to pray. He again leaves them when he is crucified and dies. Finally, 40 days after his resurrection he leaves them to ascend to Heaven. These are the incidences that readily come to mind. Perhaps one of them will answer your inquiry.
