ACTS 1:1-11
In the first book, O The-oph’ilus, I have dealt with all that Jesus began to do and teach, until the day when he was taken up, after he had given commandment through the Holy Spirit to the apostles whom he had chosen. To them he presented himself alive after his passion by many proofs, appearing to them during forty days, and speaking of the kingdom of God. And while staying with them he charged them not to depart from Jerusalem, but to wait for the promise of the Father, which, he said, “you heard from me, for John baptized with water, but before many days you shall be baptized with the Holy Spirit.” So when they had come together, they asked him, “Lord, will you at this time restore the kingdom to Israel?” He said to them, “It is not for you to know times or seasons which the Father has fixed by his own authority. But you shall receive power when the Holy Spirit has come upon you; and you shall be my witnesses in Jerusalem and in all Judea and Sama’ria and to the end of the earth.” And when he had said this, as they were looking on, he was lifted up, and a cloud took him out of their sight. And while they were gazing into heaven as he went, behold, two men stood by them in white robes, 11and said, “Men of Galilee, why do you stand looking into heaven? This Jesus, who was taken up from you into heaven, will come in the same way as you saw him go into heaven.”

EPHESIANS 1:17-23
that the God of our Lord Jesus Christ, the Father of glory, may give you a spirit of wisdom and of revelation in the knowledge of him, having the eyes of your hearts enlightened, that you may know what is the hope to which he has called you, what are the riches of his glorious inheritance in the saints, and what is the immeasurable greatness of his power in us who believe, according to the working of his great might which he accomplished in Christ when he raised him from the dead and made him sit at his right hand in the heavenly places, far above all rule and authority and power and dominion, and above every name that is named, not only in this age but also in that which is to come; and he has put all things under his feet and has made him the head over all things for the church, which is his body, the fulness of him who fills all in all.
Gospel
MARK 16:15-20
And he said to them, “Go into all the world and preach the gospel to the whole creation. He who believes and is baptized will be saved; but he who does not believe will be condemned. And these signs will accompany those who believe: in my name they will cast out demons; they will speak in new tongues; they will pick up serpents, and if they drink any deadly thing, it will not hurt them; they will lay their hands on the sick, and they will recover.” So then the Lord Jesus, after he had spoken to them, was taken up into heaven, and sat down at the right hand of God. And they went forth and preached everywhere, while the Lord worked with them and confirmed the message by the signs that attended it. Amen.
