“So when the apostles were with Jesus, they kept asking him, “Lord, has the time come for you to free Israel and restore our kingdom?”” Acts of the Apostles 1:6
In Acts chapter 1 verse 3 it says “During the forty days after he suffered and died, he appeared to the apostles from time to time, and he proved to them in many ways that he was actually alive. And he talked to them about the Kingdom of God.” Acts of the Apostles 1:3 NLT
So we know for the whole 40 days after he resurrected Jesus was with the apostles and was talking to them about the Kingdom of God. Now Jesus has told them many parables about the Kingdom of God or Kingdom of Heaven, in the book Matthew the words “Kingdom of heaven” is mentioned 31 times.
The whole time up until his death , Jesus has talked about the Kingdom of Heaven and how the 12 Apostles will be with him on the 12 thrones judging the 12 tribes of Israel
In Luke chapter 22 verses 28-30 it says
““You have stayed with me in my time of trial. And just as my Father has granted me a Kingdom, I now grant you the right to eat and drink at my table in my Kingdom. And you will sit on thrones, judging the twelve tribes of Israel.” Luke 22:28-30 NLT
And in Matthew Chapter 19 Verse 28 it says
“Jesus replied, “I assure you that when the world is made new and the Son of Man sits upon his glorious throne, you who have been my followers will also sit on twelve thrones, judging the twelve tribes of Israel.”
Matthew 19:28 NLT
Now after hearing this for a while they apostles were eager to know when it would happen this is why they kept asking if the time had come for Jesus to free israel and restore the kingdom.
Now In the next verse of Acts Jesus explains that only the father knows the date this will happen .
“He replied, “The Father alone has the authority to set those dates and times, and they are not for you to know. But you will receive power when the Holy Spirit comes upon you. And you will be my witnesses, telling people about me everywhere—in Jerusalem, throughout Judea, in Samaria, and to the ends of the earth.”” Acts of the Apostles 1:7-8 NLT
So we can see here that after Jesus ascends to heaven, the Holy Spirit will come and be upon them.
It says in John Chapter 16 Verse 7 “But in fact, it is best for you that I go away, because if I don’t, the Advocate won’t come. If I do go away, then I will send him to you.” John 16:7 NLT
Now why was it important that the Holy Spirit had to come after Jesus ascended into heaven? Well it tells us in John Chapter 14 Verse 26
“But when the Father sends the Advocate as my representative—that is, the Holy Spirit—he will teach you everything and will remind you of everything I have told you.” John 14:26 NLT
The Holy Spirit is important because he will be the thing that guides us in the right path and deliver us from temptation and sinful choices.
It tells us this in John Chapter 16 Verse 8
“And when he comes, he will convict the world of its sin, and of God’s righteousness, and of the coming judgment.” John 16:8 NLT
Now the next verses of Acts say.
“After saying this, he was taken up into a cloud while they were watching, and they could no longer see him. As they strained to see him rising into heaven, two white-robed men suddenly stood among them. “Men of Galilee,” they said, “why are you standing here staring into heaven? Jesus has been taken from you into heaven, but someday he will return from heaven in the same way you saw him go!” Acts of the Apostles 1:9-11 NLT
After Jesus ascended 2 men in white robes came down and spoke to the apostles he was explain to them that Jesus is in heaven and he will return someday the same way he left.
1 Thessalonians Chapter 4 Verse 16 says..
“For the Lord himself will come down from heaven with a commanding shout, with the voice of the archangel, and with the trumpet call of God. First, the believers who have died will rise from their graves.” 1 Thessalonians 4:16 NLT
