"The first account, O The·oph′i·lus, I composed about all the things Jesus started both to do and to teach, 2 until the day that he was taken up, after he had given commandment through holy spirit to the apostles whom he chose. 3 To these also by many positive proofs he showed himself alive after he had suffered, being seen by them throughout forty days and telling the things about the kingdom of God." Ac1:1
