stone well

Imagine time as a deep well with water below.
Is there any left? Drop a pebble and watch it go
There will always be an end to hear it splash
How long it takes, will it be a plunge or crash
The answers are hidden but the truth is known
Running forward together - to be questioned alone.
They say ‘he went too early, he shouldn’t have gone’
Until it’s too late, will I prepare for meeting the One?
