The difference between Human depravity and human inability can be illustrated by the story of the rich ruler in Luke 18:18-24
When Jesus was asked by the rich ruler what he must do to inherit eternal life, He answered: Yet lackest thou one thing: sell all that thou hast, and distribute unto the poor, and thou shalt have treasure in heaven: and come, follow me.
Please ponder the story, then ask this question. Did he go away sorrowful because he was unable to do what Jesus asked or did he not want to do it . In other words, was it a matter of ability or will. Did he not do it because he could not do it or because he was not willing to do it. Was he not willing to do it because he loved his money or he could not help but love his money.
You may say: he was in love with his money because of his depraved nature that he inherited from Adam.
If that is your answer, then you must explain how the disciples were able and willing to do the same, namely, to forsake all and follow Jesus, they too were the off-spring of Adam.
No matter what your theological conviction may lead you, you must confess that faith is a choice. If that man had faith in God, he would have given up his wealth and relied on God for provision.
If that rich ruler was under the teaching of Mr. Whitefield, he would have walked away blaming God for not loosening his bondage to his love for money.
We all agree that we are born in sin. We all agree that we have a fallen and depraved nature that creates bondage to the things of this world. But faith is the victory that overcomes the world. When we hear the words of the Lord Jesus that God who feeds the sparrows, dressed the lilies, and have our hairs numbered will take care of us if we but believe that He is and that He is a rewarder of them who diligently seek Him.
That faith will have the victory of loosening this bondage to the world.
That is what I mean by the difference between human depravity and human inability. A man can be totally depraved but when given the opportunity makes a choice to surrender to God’s rule. This question was asked before. How did Satan fall when he was perfect. Yes there was a time when Satan was perfect not only in wisdom and beauty, but also in righteousness. When I say perfect here, I do not mean infinitly perfect as God is, but as perfect as a created being can be perfect. His perfection is finite.
“Thou wast perfect in thy ways from the day that thou wast created, till iniquity was found in thee.”
There was a time when iniquity was found in Him. Why is it hard to believe that the power of choice that can give birth to iniquity in a perfectly righteous being when that being decides to rebel against God and have his own way, can not also give birth to faith when a being decides to submit to the rule of God when the latter is the most proper thing to do.
Seriously, though - with a comment like that, it's too bad the Body of Christ didn't have you around a few centuries earlier; you could have set other "false professing" guys like Spurgeon and McCheyne straight too.
I will address the latter part first. I did not say that George White field, Spurgeon and McCheyne were “false professing” guys. I am just saying that they were grievously mistaken, that’s all.
Now, the first part- Believe it or not, I strongly believe in the sovereignty of God.
As the wise preacher said: There is a time and a season for everything under heaven. In the time of the Reformation, and thereafter people needed such teaching since man turned Christian endeavor to a system of counting rosaries and climbing stairs, But we are in a time of great apostasy where grace is being used as a cloak for slackness, love for the world. Christ' imputed righteousness is nothing but a cover for sin and transgression.
