With a shout, with the voice of the archangel, and with the trump [trumpet call] of God

After Jesus commanded His disciples to not depart from Jerusalem, but wait for the promise of the Holy Ghost, Jesus was taken up 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. And while they looked stedfastly 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 1:9-11 KJV

When we have repented of our sins, been baptized in Jesus name for the remission of sins, and received the gift of the Holy Ghost, we can look forward to being resurrected from the grave as Jesus was, and going to heaven with Him when He returns for His church. (Acts 2:38, 1Thessalonians 4:14-17).

"But if the Spirit of him that raised up Jesus from the dead dwell in you, he that raised up Christ from the dead shall also quicken [give life to] your mortal bodies by his Spirit that dwelleth in you." - Romans 8:11 KJV

"But I would not have you to be ignorant, brethren, concerning them which are asleep [who have died], that ye sorrow not, even as others which have no hope. [And now, dear brothers and sisters, we want you to know what will happen to the believers who have died so you will not grieve like people who have no hope.]

“For if we believe that Jesus died and rose again, even so them also which sleep in Jesus [believers who have died] will God bring with him.

“For this we say unto you by the word of the Lord, that we which are alive and remain unto the coming of the Lord shall not prevent [precede] them which are asleep [have died]. [We who are still living when the Lord returns will not meet him ahead of those who have died.]

“For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump [trumpet call] of God: and the dead in Christ shall rise first [First, believers who have died will rise from their graves]:

“Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord. [Then, together with them, we who are still alive and remain on the earth will be caught up in the clouds to meet the Lord in the air. Then we will be with the Lord forever.]

“Wherefore comfort one another with these words. [So encourage each other with these words.]" - 1 Thessalonians 4:13-18 KJV
