1 [Dear] Theophilus, in my former letter [i.e., the Gospel of Luke] I wrote to you concerning what all Jesus did and taught since the beginning [of His ministry],
2 up until the day He returned to heaven. [Just before that time] He had given [certain] instructions to His [specially] selected apostles through [the direction of] the Holy Spirit.
3 Now, following His death on the cross [and resurrection], Jesus appeared alive [to His apostles] for forty days, and demonstrated by many convincing proofs [that He had been raised bodily from the dead]. [During that time] He also spoke to them about the [coming] kingdom of God.
