Not Robert Frost. His conceit dates back to an older time. It was old when Spenser wrote this.
My love is like to ice, and I to fire:
How comes it then that this her cold so great
Is not dissolved through my so hot desire,
But harder grows the more I her entreat?
Or how comes it that my exceeding heat
Is not allayed by her heart-frozen cold,
But that I burn much more in boiling sweat,
And feel my flames augmented manifold?
What more miraculous thing may be told,
That fire, which all things melts, should harden ice,
And ice, which is congeal’d with senseless cold,
Should kindle fire by wonderful device?
Such is the power of love in gentle mind,
That it can alter all the course of kind.Edmund Spenser
Indeed. And I would say to my PC-SJW minister: Why have you adapted Christianity to the world???
His answer would be: Heaven on earth.
So a heaven built by men rather than God – a dull copy of what will be? Even Abraham was looking further forward than this. No wonder much of Christendom looks so flaky.
