Tullian Tchividjian has an excellent blog post on the one-way love of God here: http://thegospelcoalition.org/blogs/tullian/2012/03/06/one-way-love/
Many times in our discussions about law vs. works and whether or not we should fruit check and the relationship between justification and sanctification and all of that, perhaps we miss this very point. The MAIN THING about grace is this one-way love!
If we obsess about how much we do or don’t depend on ourselves for our personal sanctification, how much even that we are theologians of the cross as opposed to theologians of glory, how much we do or don’t score-keep, it still ends up being ME DOING or even NOT DOING stuff, me catching some subtle point of theology better than I did before or – (gasp!) – better than others do.
This one way love, our identity as the pearl the great merchant wanted, is the real basis of it all. We are greatly loved, scandalously cherished. It is from a very great passion, a great desire, for US, that He died. When He died He was dreaming of us, His bride, with joy. I am that one He so loved. This is my sanctification – I live as one very greatly loved. I don’t know why He is so obsessed, and I don’t have to know. I believe it is true, and that makes a very very huge difference.
