Only God's sheep can hear his voice, not the natural man.
Your false doctrine of Total Inability is immediately refuted in scripture.
Gen 3:6 And when the woman saw that the tree
was good for food, and that it
was pleasant to the eyes, and a tree to be desired to make
one wise, she took of the fruit thereof, and did eat, and gave also unto her husband with her; and he did eat.
7 And the eyes of them both were opened, and they knew that they
were naked; and they sewed fig leaves together, and made themselves aprons.
8 And they heard the voice of the LORD God walking in the garden in the cool of the day: and Adam and his wife hid themselves from the presence of the LORD God amongst the trees of the garden.
9 And the LORD God called unto Adam, and said unto him, Where
art thou?
10 And he said, I heard thy voice in the garden, and I was afraid, because I
was naked; and I hid myself.
11 And he said, Who told thee that thou
wast naked? Hast thou eaten of the tree, whereof I commanded thee that thou shouldest not eat?
12 And the man said, The woman whom thou gavest
to be with me, she gave me of the tree, and I did eat.
13 And the LORD God said unto the woman, What
is this
that thou hast done? And the woman said, The serpent beguiled me, and I did eat.
14 And the LORD God said unto the serpent, Because thou hast done this, thou
art cursed above all cattle, and above every beast of the field; upon thy belly shalt thou go, and dust shalt thou eat all the days of thy life:
15 And I will put enmity between thee and the woman, and between thy seed and her seed; it shall bruise thy head, and thou shalt bruise his heel.
16 Unto the woman he said, I will greatly multiply thy sorrow and thy conception; in sorrow thou shalt bring forth children; and thy desire
shall be to thy husband, and he shall rule over thee.
17 And unto Adam he said, Because thou hast hearkened unto the voice of thy wife, and hast eaten of the tree, of which I commanded thee, saying, Thou shalt not eat of it: cursed
is the ground for thy sake; in sorrow shalt thou eat
of it all the days of thy life;
18 Thorns also and thistles shall it bring forth to thee; and thou shalt eat the herb of the field;
19 In the sweat of thy face shalt thou eat bread, till thou return unto the ground; for out of it wast thou taken: for dust thou
art, and unto dust shalt thou return.
20 And Adam called his wife's name Eve; because she was the mother of all living.
21 Unto Adam also and to his wife did the LORD God make coats of skins, and clothed them.
Adam and Eve sinned, and now they were spiritually dead in sin. But they could hear God when he called them and responded positively to God and came to him when he called.
So, your false doctrine of Total Inability is the very FIRST thing refuted in scripture. Never do the scriptures teach that an unregenerated sinner is UNABLE to respond to God when he calls them, in fact, the scriptures show the exact opposite of what you teach.
And the coats that God made for Adam and Eve represent the righteousness imputed to those who believe God, so this proves not only that the unregenerate can hear and respond to God positively, but they can believe and be saved.
Total Inability is false and immediately refuted in the scriptures.
