Luke 24:50-53

24:50-53 Jesus led them out as far as Bethany; and he raised his hands and blessed them; and as he was blessing them he parted from them, and was borne up into heaven. And when they had worshipped him they returned to Jerusalem with great joy; and they were continually in the Temple praising God.

The ascension must always remain a mystery, for it attempts to put into words what is beyond words and to describe what is beyond description. But that something such should happen was essential. It was unthinkable that the appearances of Jesus should grow fewer and fewer until finally they petered out. That would have effectively wrecked the faith of men. There had to come a day of dividing when the Jesus of earth finally became the Christ of heaven. But to the disciples the ascension was obviously three things.

(i) It was an ending. The days when their faith was faith in a flesh and blood person and depended on his flesh and blood presence were over. Now they were linked to someone who was forever independent of space and time.

(ii) Equally it was a beginning. The disciples did not leave the scene heart-broken; they left it with great joy, because now they knew that they had a Master from whom nothing could separate them any more.

I know not where his islands lift

Their fronded palms in air;

I only know I cannot drift

Beyond his love and care.

"I am sure," said Paul, "that nothing--nothing in life or death--can separate us from the love of God in Christ Jesus our Lord." ( Romans 8:38-39 .)

(iii) Further, the ascension gave the disciples the certainty that they had a friend, not only on earth, but in heaven. Surely it is the most precious thing of all to know that in heaven there awaits us that self-same Jesus who on earth was wondrous kind. To die is not to go out into the dark; it is to go to him.

So they went back to Jerusalem, and they were continually in the Temple praising God. It is not by accident that Luke's gospel ends where it began--in the house of God.
