Boundless Love; Boundless Sin

I've been particularly struck by the 1st verse and last line of the chorus of the song, The Glories of Calvary (Steve & Vikki Cook © 2003).
♫ Lord, You’re calling me to come, And behold the wondrous cross.
To explore the depths of grace, That came to me at such a cost.
Where Your boundless love, Conquered my boundless sin, And mercy’s arms were opened wide.
. . . ♫ Lord, take me deeper Into the glories of Calvary.
Wow!
