Total depravity is the belief that because of original sin, mankind is unable to by himself follow the word of God and thus be good and thus needs the redemptive power of Christ's sacrifice at Calvary. Most often associated with Calvinism, it is found in a wide range of Protestant denominations, mainly conservative ones.
However, reading over Deuteronomy 30:11-14 just now, it seems to me those verses at the very least weaken the traditional total depravity doctrine.
I suppose one could argue that verse 14 represents Christ in accordance with John 1, but even then since God expected man to be able to access that word well before the crucifixion, it suggests that belief in Christ's crucifixion and resurrection is not necessary to receive God's word and act upon it.
I know we have some Calvinists here, and I look forward to you defending the total depravity of man and stating why you believe these verses don't have the implications they seem to have at first glance.
