I guess I believe in them in a broad sense, not in the way Calvin address them. With total depravity I hold that yes man cannot do any good, but he can come to God by himself. With Unconditional Election I hold to the idea that we saved by grace alone and nothing we have done special. As for preservation of the Saints, I hold that once saved always saved.
Totally agree.
The thing about Total Depravity is that if we were truly dead in our trespasses and sins, then we truly lacked the capacity to "come to God". A heart that is dead cannot discern that which is spiritual - until it is quickened, or made alive by the spirit of God.
So then, even the faith to believe is a gift, lest we boast about how much faith we have.
If you're interested, check out my links to Piper. As I said, he has done his homework, and is way more eloquent then I. And most importantly, you will be blessed...
