And then this too, Jesus tells us again here why some do not believe in Him, truth is the unbelieving will not and can not receive the things of God without being born of God, then they receive Him as Lord cause they can be taught by the Spirit. Otherwise they are naturally resistant, antagonistic,
have enmity against God and Christ. Christ tell us believers the world of unbelievers hates Him because He testifies of them their works are evil.
Romans 8:6-8 is the natural state of the unsaved
New King James Version
6 For to be carnally minded is death, but to be spiritually minded is life and peace.
7 Because the carnal mind is enmity against God; for it is not subject to the law of God, nor indeed can be.
8 So then, those who are in the flesh cannot please God.
John 7:7 The world cannot hate you, but it hates Me because I testify of it that its works are evil.
'brethren beloved by the Lord, because God from the beginning chose you for salvation through
sanctification by the Spirit and belief in the truth'
Sanctification by the Spirit is Him making you born again, belief in the truth is when you believe in Him in your new creation heart, you receive Him.
Salvation is of the Lord, and it begins with Him and not us.
Look at John 1:10-13, we receive Him as we were being born of God according to His will
And
1 John 5:1 NKJV Whoever believes that Jesus is the Christ is born of God, and everyone who loves Him who begot also loves him who is begotten of Him.
1 John 5:1 ESV Everyone who believes that Jesus is the Christ has been born of God, and everyone who loves the Father loves whoever has been born of him.
John 1:10-13
10 He was in the world, and the world was made through Him, and the world did not know Him.
11 He came to His own, and His own did not receive Him.
12 But as many as received Him, to them He gave the right to become children of God, to those who believe in His name:
13 who were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God.
the action in v13 precedes what happens in v12. V12 is the reaction to the action that occurred in v13.
they receive Him because of the working power of God making them born of God
We are not born of the will of the flesh, not your will, not of your decision of your mind.
The unsaved man hates Christ and God, but they do love their false messiah's
Here we see Christ telling us people naturally do not believe in Him
Only those the Father gives to Christ come to Christ.
Then of all the Father has given to Him, God's will is none be lost.
John 6
35 And Jesus said to them, “I am the bread of life. He who comes to Me shall never hunger, and he who believes in Me shall never thirst.
36 But I said to you that you have seen Me and yet do not believe.
37 All that the Father gives Me will come to Me, and the one who comes to Me I will by no means cast out.
38 For I have come down from heaven, not to do My own will, but the will of Him who sent Me.
39 This is the will of the Father who sent Me, that of all He has given Me I should lose nothing, but should raise it up at the last day.
40 And this is the will of Him who sent Me, that everyone who sees the Son and believes in Him may have everlasting life; and I will raise him up at the last day.”
