atp,
Here is my attempt.
My understanding of total depravity or total inability is parallel with that of Jacob Arminius. Before the Fall into sin, human beings were 'good' in their ability to love and do the works of God.
Before the Fall, human beings were created in the image of God (Gen 1:26-27). According to Gen 2:17, before the Fall human beings had the ability to choose good from evil. After the Fall, for believers, they have 'put on the new self, which is being renewed in knowledge in the image of its Creator (Col 3:10 NIV).
Ephesians 2:1-2 (NIV) is a critical couple of verses in understanding Total Depravity: 'As for you, you were dead in your transgressions and sins, in which you used to live when you followed the ways of this world and of the ruler of the kingdom of the air, the spirit who is now at work in those who are disobedient'. What does it mean to be 'dead in sins'? They were spiritually dead in their former lives and this was their lifestyle (present participle). We note in Eph 1:7 the plurals, 'In him we have redemption through his blood, the forgiveness of sins, in accordance with the riches of God’s grace' (NIV). Every trespass/sin (missing the mark) demonstrated this deadness.
Does it mean that unbelievers cannot respond to God's offer of salvation? We know this is not the case because of the content of Titus 2:11 (NIV). Do sinners have a total inability to respond to the offer of salvation without God's unconditional election and irresistible grace?
We know that Adam and Eve, after they had sinned, could still hear the voice of God (Gen 3:8-19 NIV). Therefore, Total Depravity does not cut one off from hearing the voice of God. It is a demonstration of what has happened within human beings.
The crunch is this, described as total depravity, and it is that sinful human beings cannot do what is good towards God because the free will has not only been 'wounded, maimed, made infirm, bent, and weakened' but also it is 'imprisoned, destroyed, and lost'. And its powers are not only debilitated and useless unless they be assisted by grace, but it has no powers whatever except such as are excited by Divine grace'. For Christ has said, “Without me you can do nothing.”
St. Augustine, after having diligently meditated upon each word in this passage, speaks thus: “Christ does not say, without me ye can do but Little; neither does He say, without me ye can do any Arduous Thing, nor without me ye can do it with difficulty. But he says, without me ye can do Nothing! Nor does he say, without me ye cannot complete any thing; but without me ye can do Nothing.” That this may be made more manifestly to appear, we will separately consider the mind, the affections or will, and the capability, as contra-distinguished from them, as well as the life itself of an unregenerate man' (
Arminius 1977:525-526).
But the great and good news is that God has provided a way to deal with this 'dead in sin' situation: 'For the grace of God has appeared that offers salvation to all people' (Titus 2:11 NIV). This is the enabling grace of God available 'to all people' for the offering of salvation.
I believe in Total Depravity because it is a Bible teaching. It refers to comprehensive inability to do God's good because of sins and transgressions.
