Acts 1 New King James Version (NKJV)
Prologue Here we are going from the Old to the New Testament with now no longer the law but Grace as the main emphasis to show us what just happen during the time of Jesus birth to living for His Fathers will to be done  going to the Cross as His assignment to complete what He cried out Oh Lord let this cup pass from me. That was the sins of the past present and future where laid on His shoulder so we might have a new life as it is seen in the way he appeared for 40days to all. 
1 The former account I made, O Theophilus, of all that Jesus began both to do and teach, ² until the day in which ^[a]He was taken up, after He through the Holy Spirit had given commandments to the apostles whom He had chosen, ³ to whom He also presented Himself alive after His suffering by many ^[b]infallible proofs, being seen by them during forty days and speaking of the things pertaining to the kingdom of God. Notice he calls Theophilus by name a man that the Disciples knew and Luke honored by calling Him out. Lord help me to remember people names for it shows a personal awareness of who we are addressing. I admire people that know my name and I try to call people by name but it is so hard for me. Lord help us to be personal with people for everyone was created by God. Luke is telling in his way what he saw the Lord do and say. Yes, he was shocked like all the disciples but yet assured He was Lord and reign supreme. Now as Disciples they were going to see how God was still going to be present as He promised them to go on into perfection. Let’s not forget the past victories and defeats, but look at what is going to happen now to encourage them to start to speak again as they after His death went into hiding not seeing the light, but in darkness of the death of the King of Kings. Yet Jesus appears to them what a surprise for He was going to do something that would give everyone the opportunity to come alive by being born again and they were learning this the hard way. Everything that Jesus told them while He was with them now made them realize afresh He is surly the Son of God allowing us to go on into perfection. Now they are going to see a guide that is a sure foundation to build upon, they will not forget the Old Testament law, but become alive to the New Covenant that is being prepared for them as they waited upon God. Notice Jesus did and taught and confirmed what He said with many infallible miraculous works. He left us a example that proved He was a follower of Gods will by His works he taught and did. Now He is getting ready to empower the Church to do and work out their own salvation to prove they are abiding in the vine; Jesus. Jesus Christ began and the Church is going to complete what He started. We are going to see the beginning of a new Doctrine and the beginning of miracles. Jesus appears in body form, yet as a Spirit for he talked and ate with them and is soon going to leave them in the clouds. Remember it was the clouds by day that hovered over the Children of Israel in the wilderness. Now He is getting ready to do another work at the right hand of God, interceding for us His children. God is getting ready to condescend upon His chosen, showing His compassion as a High Priest that is touched with the feeling of our infirmities. He told them what was to be expected of them as chosen by Him through the Holy Spirit, which He was the Mediator that breathed upon them. The comforter was going to become the commander of the commission He gave to all present, then, now and forever. We are seeing a new Kingdom of Grace unfurl, as He tells them in secret as they are gathered what is to be expected. Notice He is in person and yet a Spirit that is going to breath upon anyone that wants to be full of His Spirit. He did not talk politics, or the kingdom of men, or philosophy, or the kingdom of nature but pure divinity and the Kingdom of Grace.
