A Missing Book?

This morning in the 24-7 Prayer Lectio 365 they were sharing on Jesus risen with this verse

1 In my former book, Theophilus, I wrote about all that Jesus began to do and to teach ² until the day he was taken up to heaven, after giving instructions through the Holy Spirit to the apostles he had chosen. ³ After his suffering, he presented himself to them and gave many convincing proofs that he was alive. He appeared to them over a period of forty days and spoke about the kingdom of God.

Acts 1:1-3

Because it says “Theophilus” at the start of both Acts and Luke it is presumed that these books were written by the same person, and that Luke was a historian as well as theologian and wanted to get things accurately shared.

The more writing I do and the more I get into editing to enter my work in competitions, etc, the more I’m looking closely at things and seeing if they make sense.

Take note here – Luke says that in his “former book” he talks about all the things Jesus did and taught till he went up to heaven and verse 3 says that over a period of forty days he “spoke about the kingdom of God”. Jesus doesn’t go up to heaven till after those forty days. According to Luke Jesus taught the disciples over this time and that he, Luke, had shared this in his former book.

The Gospel of Luke finishes with a quick summary of Jesus telling the disciples what they must do and then of him going up to heaven but to me that isn’t “all Jesus began to do and teach”. Yes there is lots in Luke’s gospel about what Jesus did before he was crucified but the 40 days after resurrection???

To my mind, if Luke was such a dedicated historian and theologian, why would he write that if there isn’t another book out there somewhere filled with the conversations and teachings that went on between Jesus and his disciples and, I think, those new followers who missed out on so much by not hanging out with Jesus before crucifixion; words and teachings that would be so helpful to us all in knowing how to live post-resurrection.
