Adamantinum Cor

Ah Lord, give me an adamantine heart:
Delve deep, divide the diamond from the rest,
And rouse it with your flame, so every part
May banish shadows and be manifest.
Against temptation make it such a shield
No point can pierce or fire dissolve its face;
To light, however, let it softly yield
Its thousand eyes as mirrors for your grace,
No spark of human love or friendship shine
Unless the jewel refract and amplify
More purely than it came, no flame divine
Conceive itself except the stone reply.
Oh, let me thus, whatever thought or yearned,
Retain the fire of love yet not be burned.
