Go into all the world and proclaim the good news to the whole creation
Mark 16/15-20: “‘Go into all the world and proclaim the good news to the whole creation. The one who believes and is baptized will be saved; but the one who does not believe will be condemned. And these signs will accompany those who believe: by using my name they will cast out demons; they will speak in new tongues; they will pick up snakes in their hands, 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 out and proclaimed the good news everywhere, while the Lord worked with them and confirmed the message by the signs that accompanied it.
John baptized with water, but you will be baptized with the Holy Spirit not many days from now.
Acts of the Apostles 01/01-14: “In the first book, Theophilus, I wrote about all that Jesus did and taught from the beginning until the day when he was taken up to heaven, after giving instructions through the Holy Spirit to the apostles whom he had chosen. After his suffering he presented himself alive to them by many convincing proofs, appearing to them over the course of forty days and speaking about the kingdom of God. While staying with them, he ordered them not to leave Jerusalem, but to wait there for the promise of the Father. ‘This’, he said, ‘is what you have heard from me; for John baptized with water, but you will be baptized with the Holy Spirit not many days from now.’ So when they had come together, they asked him, ‘Lord, is this the time when you will restore the kingdom to Israel?’ He replied, ‘It is not for you to know the times or periods that the Father has set by his own authority. But you will receive power when the Holy Spirit has come upon you; and you will be my witnesses in Jerusalem, in all Judea and Samaria, and to the ends of the earth.’ When he had said this, as they were watching, he was lifted up, and a cloud took him out of their sight. While he was going and they were gazing up towards heaven, suddenly two men in white robes stood by them. They said, ‘Men of Galilee, why do you stand looking up towards heaven? This Jesus, who has been taken up from you into heaven, will come in the same way as you saw him go into heaven.’ Then they returned to Jerusalem from the mount called Olivet, which is near Jerusalem, a sabbath day’s journey away. When they had entered the city, they went to the room upstairs where they were staying, Peter, and John, and James, and Andrew, Philip and Thomas, Bartholomew and Matthew, James son of Alphaeus, and Simon the Zealot, and Judas son of James. All these were constantly devoting themselves to prayer, together with certain women, including Mary the mother of Jesus, as well as his brothers.”
