He told them that they had to believe in Him to get the Holy Spirit, and that they should go and preach God's Word to other people so that they could also be God's children.
Peter
No the disciples did not understand him when he said you will see me for a short time only.
Jesus' disciples
Jesus broke some bread and said to the disciples this is my body and then he got some wine and said drink this, this is my blood.
They all faithly remained Jesus disciples after his death.
It means that Jesus wanted his disciples to work together and be a group of people who can be united in fellowship and in life
Jesus said this when he appeared to the disciples after the Resurrection. Jews and Muslims say it frequently - as 'Shalom'or 'Salaam'.
the disciples followed Jesus and did what Jesus said. Jesus picked his disciples. The disciples were ordinary people. Jesus doesn't only like the people who are rich and successfully. he loves us all equally, no matter who we are or what we look like, he made us all and saw that we were good
Jesus never said. It would not be in His nature to nurture envy or create competition among His disciples.
Jesus was speaking to his disciples. (Matthew 16:24) Then Jesus said to his disciples. (Matthew 16:28) Truly I say to YOU that there are some of those standing here that will not taste death at all until first they see the Son of man coming in his kingdom."
Peter was the most outspoken of the 12 disciples, he boldly said that Jesus was the son of God, he is also the only man to defend Jesus in the garden.
During the Last Supper when Jesus shared the bread and the wine He said, "As often as you do this, do so in rememberence of Me."
