Meaning of Ascension

Meaning of ascension
As we have seen, Jesus Christ's ascension is closely tied to two things. One is the resurrection, and the other is Christ being raised to the right of Heavenly Father and taking the seat of glory. To separate from these two things and just think of ascension is at least in the Bible
It's off the line. But here I'm curious about the 40 days that Luke's author suddenly brought in when he wrote Acts. Why was the Ascension of the Lord staggered 40 days after the day of the resurrection?
I would like to think about the reason for this.

If we look at the Luke Gospel and the Book of Acts as a series, there is a long path leading to one. First, the Luke Gospel describes the life of Lord Jesus as a journey. This journey has three stages. 1) Inside Galilee. 2) The road to suffering until suffering from suffering 3) The way of suffering itself to death on the cross. This is one step, but simultaneously represents two movements. One is a movement that shows a voice from heaven when the Lord is baptized by John the Washer. "You are my dear one, my heart's worth" (Luke 3; 22). This is an ascending movement from bottom to top, receiving the glory and honor of the Son from the Father. However, the process of glory itself is, in fact, a downward movement, which suddenly drops to suffering and death on the cross. Luke's Gospel makes these two seemingly inconsistent movements a journey. The ascending movement ends with a resurrection and ascension that receives glory as the Son of God. In this sense as well, the Gospel says resurrection and ascension are on the same day, and in terms of meaning they are not so different.

But then, did Lord Jesus' earthly journey end when he took the right seat of Heavenly Father at the time of the resurrection?
Actually, it's not over yet. The author of Luke wrote Acts as a continuation of the Gospel. And so, these Acts also show another movement different from the Gospel. So the whole Acts is the work of Lord Jesus, who sits to the right of the Father. It is expressed as a powerful movement of the spirit, in which Christ's salvation spreads throughout the world by the work of the Apostles' Church. Let's take a closer look at this movement. Acts are divided into two parts. Some describe the work of the apostle Petro (from the beginning to chapter 12). The other half describes the role of the apostle Paul. The church that centers on these two apostles is based on the Holy Spirit, the spirit of Jesus Christ. All of that is the work of the Spirit, and ultimately the work of the Lord Jesus, who sent the Holy Spirit. Working and summarizing this movement, it first starts from a gathering of 12 apostles in Jerusalem.
There are various oppositions and difficulties, conflicts within the church, misunderstandings, and persecution from the outside. Faith spreads without losing it. The word of God finally enters the center of the world, Rome, and then spreads throughout the world. This spreading movement had already been announced since the beginning of Acts. "But when the Holy Spirit falls upon you, you will be empowered and will be my witnesses to Jerusalem, the whole of Judea and Samaria, and to the ends of the earth" (Acts of the Apostles1; 8). This is not about the apostles. The work of the Spirit of the Lord, which works through the apostles to the ends of the earth, is being carried out. "
