The natural man, as described in 1 Cor 2:14, cannot discern the things of the Spirit until he has been born again with the indwelling of the Holy Spirit (Eph 2:5). He cannot believe in spiritual things.
That was the Saint Apostle Paul and his companion Sosthenes letter to the church in Corinth.
Reminiscent of his time as a Pharisee, when he said natural man cannot discern the things of the spirit.
If it were true fallen man and woman could not discern the spiritual things, Jesus , who said He came not for the righteous but for the sick, the sinners, would have been wasting his time standing near the lake of Gennesaret and speaking to a people who you believe could not understand.
The Book of Luke chapter 5
Jesus Calls the First Disciples
1. On one occasion, while the crowd was pressing in on him to hear the word of God, he was standing by (
A)the lake of Gennesaret, 2 (
B)and he saw two boats by the lake, but the fishermen had gone out of them and were (
C)washing their nets. 3 Getting into one of the boats, which was Simon's, he asked him to put out a little from the land. And (
D)he sat down and taught the people from the boat. 4 And when he had finished speaking, he said to Simon, (
E)“Put out into the deep and let down your nets for a catch.” 5 And Simon answered, “Master, (
F)we toiled all night and took nothing! But at your word I will let down the nets.” 6 And when they had done this, (
G)they enclosed a large number of fish, and (
H)their nets were breaking. 7 They signaled to their partners in the other boat to come and help them. (
I)And they came and filled both the boats, so that they began to sink. 8 But when Simon Peter saw it, he fell down at Jesus' knees, saying, (
J)“Depart from me, for (
K)I am a sinful man, O Lord.” 9 For he and all who were with him were astonished at the catch of fish that they had taken, 10 and so also were James and John, sons of Zebedee, who were partners with Simon. And Jesus said to Simon, “Do not be afraid; from now on you will be catching men.”[
a] 11 And when they had brought their boats to land, (
L)they left everything and followed him.
The men that were to be Jesus' Disciples , the reason Jesus performed miracles before the people, was to show everyone watching, truth in action.
In Jesus time there were many false teachers. And likely many claiming to be the messiah.
Jesus however, was Messiah and He showed the people The Word, that is God, giving life to the words spoken by the man they beheld as just a man and named Jesus.
Jesus showed them, gave them knowledge of the truth, when the parable of the fisherman and the empty boats was beheld by all there to witness it.
Without God, we are empty. Our nets are empty of sustenance, fish, God. But with God, Jesus in the boat telling the fishermen to cast their nets out again, to have faith, we are full. Which is why the empty nets cast out were miraculously filled up when Jesus was there telling the people why they should have faith. And then showing them what having faith would do for their lives.
A people who sustain themselves on fishing get the message. Jesus literally led by example.
And people came then to the knowledge of the truth and had faith.
Jesus would have not had to do any of the miracles He did to show God's word in action, if man has no part in their coming to faith. When God makes a person to be in His grace, and then makes them to have faith, because that is a teaching that first says, man has no free will and is so totally immorally depraved as to be unable to come into faith of their own accord, that is saying God is actually changing in all of humanity what He created in the beginning all humanity to be; totally depraved.
God is no respecter of persons. God is not a man that he should lie. God does NOT change!
Your theology is error.
