"Love Lustres at Calvary"

I was reading in The Valley of Vision this morning and encountered the following passage. I love the imagery and the reality to which it points.

My Father, enlarge my heart, warm my affections, open my lips,
   supply words that proclaim 'Love lustres at Calvary.'
There grace removes my burdens and heaps them on thy Son,
   made a transgressor, a curse, and sin for me;
There the sword of thy justice smote the man, thy fellow;
There thy infinite attributes were magnified,
   an infinite atonement was made;
There infinite punishment was due,
   and infinite punishment was endured.
