There is a post from a week ago that discussed the identity of Theophilus, so let us move on from that.
I would note that we have here I & II Luke, or 1 & II Theophilus. Try telling someone to turn to II Theophilus. Some will get it.
Now note the subject matter of the two books: the former was about what Jesus BEGAN to do and teach. If the former was about what Jesus began to do, then do you suppose the second book is about what Jesus CONTINUED to do and teach? AMEN.
As you read through the entire book you will see that it is all about what JESUS was doing, the risen Lord was the "same Jesus" (Acts 2:36). And the "Same Jesus" is the one who did all the miracles found in Acts.
Here would be a great reading exercise:
In the Book of Acts, the sequel to the Gospels, the term "Lord" is used interchangeably to refer to the One God in heaven (Acts 1:24; 2:20-21) and to the Lord Jesus who had been with them on the earth (Acts 1:6, 21; 2:21-36). In many passages it is difficult to determine whether the word �Lord� points to Jesus or to God, or as it develops, to both, to Jesus as the Lord God of eternity (Acts 2:36, 47; 5:14).
EXERCISE: A powerful exercise would be to read through the entire book of Acts, looking for the term �Lord,� and circling or highlighting every occurrence. Then ask yourself who is �the Lord?� This Lord is the God of Heaven. This Lord is Jesus of Nazareth (Acts 9:27-42). Peter, who early on recognized the true divine identity of Jesus (Matt. 16:13-17; Acts 2:36), now in preaching to the Gentiles plainly declares the meaning of Jesus� Lordship: He is Lord of All (Acts 10:36). Jesus is the Lord and God is the Lord (Acts 11:20-24; 13:46-49; 14:23). The Lord Jesus bestows the grace by which we are saved (Acts 15:11).
How long do you think it would take you to read the entire book of Acts and CIRCLE every appearance of the word "Lord?"
