He was lifted up

Go therefore make disciples of all the nations.
I was reading this summoning line.
Normally I just carry on half believing faith’s obligations.
Now for an instant, I knew He had said this and given this sign.
Was this the working of the Holy Spirit?
Is this why we can witness
That we can do nothing on our own, every small victory is pyrrhic.
And then only for an instant of concentration from life’s business.
As He said this He was lifted up.
Rationally does that make sense, like turning off a light?
Or like a rocket disappearing, rising up?
No, He just vanished from our sight.
But this I understand from that instant of lasting value.
I knew it was absolutely true.
