Acts 1:1-3.

"The former account I made, O Theophilus, of all that Jesus began both to do and teach, until the day in which He was taken up, after He through the Holy Spirit had given commandments to the apostles whom He had chosen, to whom He also presented Himself alive after His sufferings by many infallable proofs, being seen by them during forty days and speaking of things pertaining to the Kingdom of God."

 

God bless you.
