What struck me about the song, especially given the song's popularity in evangelical circles, is that, well, it's a song that beautifully expresses the theology behind universal reconciliation. Seriously, if you sing this song you believe in universal reconciliation.
From the chorus of "Unstoppable Love":
God, You pursue me, with power and gloryGod's love is unstoppable, unrelenting and it never ends. Not even death can stop it. I don't know how this song, theologically, avoids being a song about universal reconciliation.
Unstoppable love that never ends
You're unrelenting, with passion and mercy
Unstoppable love that never ends
No sin, no shame, no past, no pain
Can separate me from Your love
No height, no depth, no fear, no death
Can separate me from Your love
Well, I guess you can sing this song if you endorse the doctrine of election that God's love is "unstoppable" for the very few people whom God elects, the belief that God's love is "unstoppable" if God happens to love you. And if not? Sucks to be you!
But if you believe what 1 Timothy 2.4 says, that God "desires all people to be saved," and that God's love is "unstoppable," I don't know how you avoid the inevitable conclusion of universal reconciliation.
