I did not contradict anything.
I said the unbeliever cannot understand spiritual wisdom from God or live in the Spirit. That does not mean an unbeliever cannot understand a perfectly clear command to "Repent and believe the gospel", or be aware of their sinful state and need of a Savior under the conviction of the Holy Spirit.
When God gives a command and warns of punishment for those who do not comply, as though they are responsible agents, it certainly does imply the ability to obey. Whether in the OT or the NT God's commands never seemed to be presented as impossibilities for the hearers, as if they lacked the ability to understand the directive or respond. “Come now, and let us reason together,” Says the Lord, “Though your sins are like scarlet, They shall be as white as snow; Though they are red like crimson, They shall be as wool. (Isaiah 1:18)
Truly, these times of ignorance God overlooked, but now commands all men everywhere to repent, because He has appointed a day on which He will judge the world in righteousness by the Man whom He has ordained. (Acts !7:30-31)
The Calvinist teaching of total inability does seem to be a contradiction to the scriptures because it opposes the Bible teaching concerning hardness of heart. The Scriptures warn us that those who repeatedly participate in sin may sear their consciences ...
Now the Spirit expressly says that in latter times some will depart from the faith, giving heed to deceiving spirits and doctrines of demons, speaking lies in hypocrisy, having their own conscience seared with a hot iron (1 Tim. 4:2)
and render themselves "past feeling"...
This I say, therefore, and testify in the Lord, that you should no longer walk as the rest of the Gentiles walk, in the futility of their mind, having their understanding darkened, being alienated from the life of God, because of the ignorance that is in them, because of the blindness of their heart; who, being past feeling, have given themselves over to lewdness, to work all uncleanness with greediness.(Ephesians 4:19)
entering into a hardening of the heart toward God and His truth.
Contrary to Calvinism's doctrine of Total Inability, the Bible teaches that people resist the Holy Spirit and do not believe, not because they are unable to understand, but because they refuse and do not want to submit to God...
You stiff-necked and uncircumcised in heart and ears! You always resist the Holy Spirit; as your fathers did, so do you. Acts 7:51
