Ok I will take a swing at it
If man is totally depraved, cannot seek God, cannot think a right though about God, cannot know truth as the "T" in tulip infers, then why did God have to say 3 times He had to give these unbelieving reprobates over ?
Also is man is so utterly depraved , dead ( corpse like ) , deaf, blind state etc...... then why would Jesus have to hide the truth from the dead, deaf, blind with parables ? That would be unnecessary since they cannot possibly understand anything id they were dead like a corpse.
You are confusing the state of man apart from God in the world, with the state of God's people who were called out of the world.
The parables were hidden from his enemies the Pharisees, who had good working knowledge of Scripture, and were seeking a reason to kill him.
Also how can these reprobates suppress the truth since they are dead and incapable of knowing the truth ?
You are confusing the state of man apart from God with God's called-out people.
Romans 1 deals with mankind apart from God, pre-Abraham.
The wrath of God is being revealed from heaven against all the godlessness and wickedness of people, who suppress the truth by their wickedness, 19 since what may be known about God is plain to them, because God has made it plain to them. 20 For since the creation of the world God’s invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made, so that people are without excuse.
21 For although they knew God, they neither glorified him as God nor gave thanks to him, but their thinking became futile and their foolish hearts were darkened. 22 Although they claimed to be wise, they became fools 23 and exchanged the glory of the immortal God for images made to look like a mortal human being and birds and animals and reptiles.
24 Therefore God gave them over in the sinful desires of their hearts to sexual impurity for the degrading of their bodies with one another. 25 They exchanged the truth about God for a lie, and worshiped and served created things rather than the Creator—who is forever praised. Amen.
26 Because of this, God gave them over to shameful lusts. Even their women exchanged natural sexual relations for unnatural ones. 27 In the same way the men also abandoned natural relations with women and were inflamed with lust for one another. Men committed shameful acts with other men, and received in themselves the due penalty for their error.
28 Furthermore, just as they did not think it worthwhile to retain the knowledge of God, so God gave them over to a depraved mind, so that they do what ought not to be done.
Several reasons why I think the doctrine of TD is not true
1-they suppressed the truth- one has to know the truth to suppress the truth
No, one thinks what they are suppressing is falsehood.
2-they knew God, He was self evident to them
Creation was then, and is now, irrefutable testimony of a God. And if there is God, his own conscience tells him God is to be glorified and thanked.
3-God was understood to them
His divine nature and eternal power are clearly seen in creation.
4-they exchanged the truth
They exchanged the truth they knew of the existence of God for idols made in the image of man, birds, animals and reptiles.
5-they did not retain the knowledge of God, it was not worthwhile for them
And in judgment, God gave them over to a depraved mind, the emptiness of which left a vacuum which sucked in darkness.
6- Therefor from all the above facts God declares 3 times that He gave them over
Because of their idolatry (spiritual whoredom), he gave them over to
sexual immorality, exchanging the truth of God for a lie,
homosexuality, shameful lusts, exchanging natural relations for unnatural ones,
depraved minds, filled with every kind of wickedness, evil, greed and depravity,
not only doing these things themselves, but also approving of others who practiced them.
7- God doesn't need to give anyone over who is already completely unable, enable, completely and totally depraved with no ability's to do otherwise
God punished sin with more sin, which is consistent throughout the OT.
8- parables would not be necessary if TD were true and men are in corpse like state by birth.
The Gentiles of Ro 1 were in corpse like state by birth, the Pharisees were the people of God hundreds of years later.
Rom 2:14 For when the Gentiles, which have not the law, do by nature the things contained in the law, these, having not the law, are a law unto themselves:
Totally Depraved would imply that one is never able to do what is right and lawful; scripture states that man naturally can keep the law.
Scriptures states that conscience
knows the law, not that it can
keep the law to God's specifications.
