Jesus appeared to the disciples for 40 days after His resurrection and then ascended to Heaven. Here are two accounts of the Ascension of Jesus from the Gospel of Matthew and from the Acts of the Apostles.
16 “Now the eleven disciples went to Galilee, to the mountain to which Jesus had directed them. 17 When they saw him, they worshiped him; but some doubted.” 18 And Jesus came and said to them, “All authority in heaven and on earth has been given to Me. 19 Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, 20 and teaching them to obey everything that I have commanded you. And remember, I am with you always, to the end of the age.” Matthew 28:16–18
7 He replied, “It is not for you to know the times or periods that the Father has set by his own authority. 8 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.”
9 When he had said this, as they were watching, he was lifted up, and a cloud took him out of their sight. 10 While he was going and they were gazing up toward heaven, suddenly two men in white robes stood by them. 11 They said, “Men of Galilee, why do you stand looking up toward 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.” Acts 1:7–18
10 “He who descended is the same one who ascended far above all the heavens, so that he might fill all things.) 11 The gifts he gave were that some would be apostles, some prophets, some evangelists, some pastors and teachers, 12 to equip the saints for the work of ministry, for building up the body of Christ.” Ephesians 4:10–12
2 “In my Father’s house there are many dwelling places. If it were not so, would I have told you that I go to prepare a place for you? 3 And if I go and prepare a place for you, I will come again and will take you to myself, so that where I am, there you may be also.“
4 “And you know the way to the place where I am going.” 5 Thomas said to him, “Lord, we do not know where you are going. How can we know the way?” 6 Jesus said to him, “I am the way, and the truth, and the life. No one comes to the Father except through me.” John 14:2–6
