Remembering that Jesus will come to Earth again and do mighty works before the end of the world, His last recorded physical act on Earth was His ascension into heaven.
After His resurrection, Jesus stayed with His disciples for 40 days, teaching them about the kingdom of God and how to administer His church.
On His last day with them, Jesus and the disciples walked from Jerusalem to a town on the Mount of Olives called Bethany. Jesus commanded the disciples to not leave Jerusalem until they received the Holy Ghost, which the Father had promised to give them.
They asked Jesus if He planned to restore the kingdom of Israel. He told them,
“It is not for you to know the times or the seasons, which the Father hath put in His own power.
But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judæa, and in Samaria, and unto the uttermost part of the earth” (Acts 1:7-8.)
At that time, the disciples assumed Jesus meant that they would share the Gospel with only Jews throughout the world.
Then something extraordinary happened! Jesus ascended into heaven.
“And when he had spoken these things, while they beheld, he was taken up; and a cloud received him out of their sight” (Acts 1:9.)
Mark recorded “So then after the Lord had spoken unto them, He was received up into heaven, and sat on the right hand of God” (Mark 16:19.)
As Jesus departed, two angels appeared to explain what happened and prophesied Jesus’s return to the disciples.
“And while they looked steadfastly toward heaven as he went up, behold, two men stood by them in white apparel;
Which also said, Ye men of Galilee, why stand ye gazing up into heaven? this same Jesus, which is taken up from you into heaven, shall so come in like manner as ye have seen Him go into heaven” (Acts 1:10-11.)
Then the group obediently returned to Jerusalem to await the promised Holy Ghost before they began spreading the Gospel throughout the world.
After His ascension into heaven, though not physically present, New Testament writers recorded that Jesus interacted with people, like appearing in visions or performing miracles. So although Jesus ascended into heaven, His work certainly continues.
