Read Acts 1 today.

This is the ‘sequel’ to the Gospel of Luke. It includes the events that took place in the early church after Jesus’ resurrection.
In verse 3, we read that Jesus appeared to His disciples ‘from time to time’. (This is according the NLT. Other translations do not make this distinction, but only that Jesus appeared to them during the the 40 days. ‘From time to time’ is a reasonable translation, since there is no clear mention of Jesus staying with them.)
Yet this makes me wonder, for what reason would Jesus not stay with them throughout that time? Surely there was much to teach and discuss. Why not stay to maximize the time with them?
I wonder if it might be related to Jesus preparing them to be His witnesses in His absence. If Jesus remained physically present, they would never have become His witnesses, they would have merely directed inquiries to Him. But Jesus’ desire was, and is, for His followers to be witnesses. We learn His story, and incorporate His story into our own. Then, with our lives and our mouths, we share His story.
How are you doing as a witness for Jesus?
Acts 1:3, 6-8 NLT
During the forty days after he suffered and died, he appeared to the apostles from time to time, and he proved to them in many ways that he was actually alive. And he talked to them about the Kingdom of God.
[6] So when the apostles were with Jesus, they kept asking him, “Lord, has the time come for you to free Israel and restore our kingdom?” [7] He replied, “The Father alone has the authority to set those dates and times, and they are not for you to know. [8] But you will receive power when the Holy Spirit comes upon you. And you will be my witnesses, telling people about me everywhere-in Jerusalem, throughout Judea, in Samaria, and to the ends of the earth.”
