In the first book, O Theophilus, I have dealt with all that Jesus began to do and teach,
First book… began to do and teach
Luke is the author of the book of Acts. He is also the author of the gospel of Luke. He is conducting a research project that takes him from the birth of Jesus to the birth of the church. Theophilus is the person to whom Luke wrote both books.
We know that Luke was a doctor and his writing is meticulous. Of all the gospel writers he is the most detailed and thorough. He uses words precisely. When he says his first book was what Jesus began to do and teach we need to take note. The first work is the gospel of Luke where Jesus is the lead character from start to finish, but in this second work, the book of Acts, Jesus is going to make a brief appearance and depart the scene.
How are we to understand the word “began”? Luke tells us that Jesus is going to continue both doing and teaching. How? The way this is written is supposed to make us lean in and look for the answer right at the outset. We are supposed to enter here looking over the shoulder of the resurrection man, listening to a dead man teach about how to live in light of his destruction of the laws of sin, death, and physics. He is going to continue doing things and teaching us things and we’d better pay attention. He is no longer the peasant prophet, he is now the ruler of life and death. We listen in on the conversation and find out that he is not planning on sticking around and that some other person (thing, event) is going to shape and guide the movement he has begun.
It is the Holy Spirit. It is not an it but a he. A person. He is the Spirit of Christ. What does that mean? It means we should look for and expect Him to act like Jesus and to do the kinds of things Jesus did and say the kind of things Jesus said. He is not unknown to us. The whole gospel of Luke tells us what to expect from Him. Now we wait to see how He will arrive on the scene and what the gospel of Acts will be.
