It appears that you do not believe that all natural men (people) are depraved. How do you interpret Psalms 53:2? This is describing what God saw by his foreknowledge, which brought him to the decision to choose an elect people and have his Son to pay for the sins of their depraved nature.
Again, you say you believe all scripture must harmonize in order to gain the proper understanding of a topic and then you excerpt verse 2 of David's song of the Book of Psalms 53.
If people are what a Calvinist believes as you argue as one here, that the T in Calvin's TULIP formula, "Total Depravity", were true then the full import of Total as regards the accusation of the human family being Depraved would preclude the totally depraved from possessing the capacity to repent.
See how TULIP fails? Especially when conflating the TULIP formula with the idea that God died only to save those whom He predetermined would respond to His leading unto repentance and salvation.
When someone is totally depraved they would be unable to acknowledge the leading of God because they are totally unprincipled.
And if the Calvinist argument then responds with, but God can bypass that barrier of total depravity when calling to himself those whom he chose to redeem himself, then we're back to square one wherein the Calvinist doctrine presupposes that God is an unprincipled ogre that creates before the world people he would choose to save after he created people he knew would fall into sin in the garden so as to need saving.
And conversely, He created people whom he knew would die in their sins and enter Hell.
That's Calvin's doctrine. God, the Sadist.
While his TULIP principle contradicts itself in the latter four points due to the declaration in the first, Total Depravity.
Total Depravity (also known as Total Inability and Original Sin)
Unconditional Election
Limited Atonement (also known as Particular Atonement)
Irresistible Grace
Perseverance of the Saints (also known as Once Saved Always Saved)
T= Man's heart is evil.
U=God chooses certain evil hearted people to be saved due to his reasons, not anything the depraved immoral evil hearted chosen one's do so as to claim they warranted being chosen.
L=Jesus died to install the concept of Limited Atonement into the world. While the scriptures claim Jesus died so that whosoever believes in Him will not perish, in truth his death was not efficacious, effective, so as to save whosoever believed in him. Instead, His death was actually to redeem only those totally depraved people God chose to save because they are incapable by that fallen nature to choose Him themselves. Which means all those scriptures about Jesus dying for all who would come unto repentance is a lie. (per Calvin)
Irresistible Grace = Is whenGod calls those totally immoral depraved persons incapable of hearkening unto the goodness in God's word of themselves, their own effort, due to their being totally depraved, they cannot resist.
However, prior to that having an affect on that totally depraved immoral chosen one, they were incapable of finding God on their own, now though we're told they will be unable to resist God calling them to Himself because their Total Depravity isn't real. Else they'd be totally unable to respond to righteousness becasue they are first and foremost born entirely immoral, therein they would not recognize a moral leading. Unless, God's plan created all people to be Totally Depraved due to the sin in the garden and then decided who's TD shields would be able to be penetrated by His decision to save them after His will caused them to be born totally depraved having also the foreknowledge that one born that way is that one he would later save from himself and the damned judgment afforded by Himself.
Irresistible Grace claims God offers to all people the gospel message. And yet the concept of Irresistable Grace insures His sacrifice and message was began because He only intended to have the Good News deliver itself unto those He created totally depraved so that He could rescue them from that station he implanted into them in the beginning before humans were created.
It also means God foreknew whom He would damn among those that remain Totally Depraved. It also means that when He taught that He came to save the world and all who believe that he actually meant He came to save only those whom He predetermined He would save of His own merit not theirs.
Saved against your will. By the God that made you totallPy depraved so as to have no will capable of accepting the moral message in the gospel itself.
P= Perseverance of the Saints , no kidding! Those God elects to save from the T formula he foreordained can never lose what they never had anything to do with in achieving it for themselves in the first place. They are forever saved because God Elected to save them before he created the whole world and humans. Which necessarily points to the converse. That God created the world to be full of depraved people damned for their condition and yet predestined from among that worldly number those one's HE would save himself through his own efforts alone.
Which would mean Jesus didn't have to die at all. Because no human needed to have faith in His sacrifice for the world's sins when He had already predetermined who among the worlds population that in total are depraved would be saved by His choice before the world began.
In short, Jesus didn't have to die to save anybody when God, who later was Jesus, had already determined whom He would save before the first human was created, because there is no thing that Elect one does to save themselves per the TULIP formula. It is all God. Therefore God didn't have to die in order to give anyone opportunity to have faith in the cause of His sacrifice when only those He predetermined would be saved from that born state of Totally Depraved would be chosen by Him to be saved from Him as the judge who would later cast others not chosen into Hell.
