God Knows our Hearts and knows who's heart will be receptive to His Gospel ----and God allows the people who's hearts are hardened toward Him and His Word to have their way ----God does not Force people to come to Him ----we have free will to Choose LIFE or DEATH -----
You are correct, God does know that, and by that He also knows that no one of themselves will/can be receptive to His word.
He knows the heart of natural man is deceitful above all things.
[Jer 17:9 KJV] 9
The heart [is] deceitful above all [things], and desperately wicked: who can know it?
He knows that natural man, being natural man, is unrighteous; that they have no spiritual understanding; that none can seek after Him
[Rom 3:10-12 KJV]
10 As it is written, There
is none righteous, no, not one:
11 There is
none that understandeth, there is none that seeketh after God.
12 They are
all gone out of the way, they are together become unprofitable; there is none that doeth good, no, not one.
He knows that He alone must give them a new heart, new spirit and a renewed mind, which only comes from salvation.
Until and unless saved, they will never come to true spiritual wisdom.
[Eze 36:26 KJV]
26
A new heart also will I give you, and a new spirit will I put within you: and I will take away the stony heart out of your flesh, and
I will give you an heart of flesh.
[Rom 12:2 KJV]
2 And be not conformed to this world: but
be ye transformed by the renewing of your mind, that ye may prove what [is] that good, and acceptable, and perfect, will of God.
He knows that natural man is spiritually dead in sin and being spiritually dead, incapable of doing anything to give themselves spiritual life - that He must first forgive their sins, and from that, they obtain spiritual life; from spiritual life, comes spiritual understanding, not the reverse.
[Eph 2:1 KJV]
1
And you [hath he quickened], who were dead in trespasses and sins;
[Col 2:13 KJV]
13 And you, being dead in your sins and the uncircumcision of your flesh,
hath he quickened together with him,
having forgiven you all trespasses;
He knows that by the wisdom of natural man, that natural man can never find wisdom.
[1Co 2:13-14 KJV]
13 Which things also we speak,
not in the words which man's wisdom teacheth, but which the Holy Ghost teacheth; comparing spiritual things with spiritual.
14 But the
natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know [them], because they are spiritually discerned.
He knows that natural man cannot even understand the tenets of salvation until their sins have first been forgiven them
[Luk 1:77 KJV]
77
To give knowledge of salvation unto his people by the remission of their sins,
He knows that we are all completely dependent upon His grace and mercy for salvation - which mercy and grace He
does not impart to everyone - we can contribute nothing to the receiving of it but to be its recipients: it cannot be purchased, nor
deserved, nor taken by force, nor by works - it is completely and in its fullness a gift from Him alone in all ways, given only to those whom He has chosen for it, it being out of the reach or power of man. Should we have to make any contribution at all for it, then we would be co-saviors with Christ, but Christ alone is the Savior.
Instead, we are first saved, and from/by that, given the attributes of salvation which follow it - those of a Christian - such as true faith - which come through the indwelling of the Holy Spirit.
You do believe that Christ is the Savior, don't you? If so, then what do you think that being Savior actually means?
[Jde 1:25 KJV] 25 To
the only wise
God our Saviour, [be] glory and majesty, dominion and power, both now and ever. Amen.
