Well explained brethren.
One small point to be seen here as well. The fact that the word of God is, indeed, the word of God.
The apostles say that they had reached the world and had been made known to all nations and yet people will argue that it has not.
When the word of God says it is done. It is done.
Here Jesus says he cannot be touched because he hasn't yet ascended. Later on he allows himself to be touched.
If the word of God is the word of God then... clearly... between the 2 incidences... Jesus ascended.
Let the word be the word.
