“… you will receive power when the Holy Spirit has come on you, and you will be My witnesses in Jerusalem, in all Judea and Samaria, and to the ends of the earth.”
After He had said this, He was taken up as they were watching, and a cloud took Him out of their sight. While He was going, they were gazing into heaven, and suddenly two men in white clothes stood by them. They said, “Men of Galilee, why do you stand looking up into heaven? This Jesus, who has been taken from you into heaven, will come in the same way that you have seen Him going into heaven.”
Then they returned to Jerusalem from the mount called the Mount of Olives, which is near Jerusalem—a Sabbath day’s journey away.
— Acts 1:8-12, HCSB.
The Festival of the Ascension is important because it emphasizes the physicality of our salvation. Christ did not evaporate after his Easter resurrection, instead he appeared to hundreds of people over the course of 40 days. He touched them, he ate with them, he spoke with them. He left hundreds of witnesses. He lived in time and space. He stood on a real mountain, and rose from a real place. He was one of us, and still is one of us.
Though he ascended into heaven, a higher dimension, so that he could fill the entire universe, he is still a human being. (Ephesians 4:10).
Coming exactly 40 days after Easter, Ascension Day liturgically reminds us that Christ tarried here, and gave us many witnesses, and that his calling was not just to pay for sin, but also to bring us to be with him. That is why he waited and stayed, to give us faith through the word of truth preached by his apostles. It was his resurrection and the proof of his resurrection that he gave, that made the apostles bold. They touched him, they saw him ascend.
The One who descended is also the One who ascended far above all the heavens, that He might fill all things. And He personally gave some to be apostles, some prophets, some evangelists, some pastors and teachers, for the training of the saints in the work of ministry, to build up the body of Christ, until we all reach unity in the faith and in the knowledge of God’s Son, growing into a mature man with a stature measured by Christ’s fullness. Then we will no longer be little children, tossed by the waves and blown around by every wind of teaching, by human cunning with cleverness in the techniques of deceit. But speaking the truth in love, let us grow in every way into Him who is the head—Christ. From Him the whole body, fitted and knit together by every supporting ligament, promotes the growth of the body for building up itself in love by the proper working of each individual part.
— Ephesians 4:10-16, HCSB.
Heaven is our home. Happy Ascension!
