I have encountered RS Thomas before - he appears to speak to me just at the right moment. The full text of the poem can be read below. It strikes me he is showing us that mysterious, loving power we call God is always there, if only we would see. And sometimes we do see for a moment, but then we tend to pass on by and somehow forget - such is ordinary man's experience.
I have seen the sun break through
to illuminate a small field
for a while, and gone my way
and forgotten it. But that was the
pearl of great price, the one field that had
treasure in it. I realise now
that I must give all that I have
to possess it. Life is not hurrying
on to a receding future, nor hankering after
an imagined past. It is the turning
aside like Moses to the miracle
of the lit bush, to a brightness
that seemed as transitory as your youth
once, but is the eternity that awaits you.
