Total Depravity as defined by Calvinists: Confession of Faith, Chapter IX, Section iii. -- "Man, by his fall into a state of sin, hath wholly lost all ability of will to any spiritual good accompanying salvation; so as a natural man being altogether averse from that good, and dead in sin, is not able, by his own strength, to convert himself, or to prepare himself thereunto." Hardening as defined in Scripture: Self Hardening-- the unwilling stubbornness of man that leads to a calloused and unresponsive heart so that they cannot see, hear, understand and be converted. (Matt. 23:37; Acts 28:26-27; John 12:37-41) Zech. 7:11-13: "Your ancestors would not listen to this message. They turned stubbornly away and put their fingers in their ears to keep from hearing. 12 They made their hearts as hard as stone, so they could not hear the law or the messages that the LORD Almighty had sent them by his Spirit through the earlier prophets. That is why the LORD Almighty was so angry with them. 13 "Since they refused to listen when I called to them, I would not listen when they called to me, says the LORD Almighty. Other examples (Ex. 9:34-35; 2 Chron. 36:13; Zech. 7:12; Dan. 5:20; Eph. 4:18; Heb. 3:12-15) Judicial Hardening -- God's sealing of people in their own rebellion in order to accomplish His Soveriegn purpose through them. Ro 11:8 - Just as it is written: "God has given them a spirit of stupor, Eyes that they should not see And ears that they should not hear, To this very day." John 12:39-40 Therefore they could not believe, because Isaiah said again: "He has blinded their eyes and hardened their hearts, Lest they should see with their eyes, Lest they should understand with their hearts and turn, So that I should heal them." Other examples of Judical hardening (Ex. 7:3; 9:12; Deut. 2:30; Josh 11:19-20). Is God unjust in this, for if God hardens who can resist his will? Romans 9:18-21 answers this objection. It doesn't answer the objection, "If we are all born Total Depraved how can God still blame us," as many Calvinists think. Romans 9-11 is dealing with the issue of Hardening, not Total Depravity, therefore the objections to Total Depravity still stand. Therefore the objection stands: How can God judge his creation for not following a command that he has not enabled them to follow? If all are born Totally depraved and unable to respond to the call of the gospel by God's imputing the sin of Adam upon all man, then God would be unjust in condemning those he disabled by that imputation while arbitrarely granting the ability to others.
