This is what stands out to me. Not being given a heart to know what? Or eyes to see what? Or ears to hear what? John 5:36-47 But I have greater witness than that of John: for the works which the Father hath given me to finish, the same works that I do, bear witness of me, that the Father hath sent me. [37] And the Father himself, which hath sent me, hath borne witness of me.
You have neither heard his voice at any time, nor seen his shape. [38] And you have not his word abiding in you: for whom he has sent, him you believe not. [39] Search the scriptures; for in them you think you have eternal life:
and they are they which testify of me. [40] And you will not come to me, that you might have life. [41] I receive not honour from men. [42]
But I know you, that you have not the love of God in you. [43] I am come in my Father's name, and you receive me not: if another shall come in his own name, him you will receive. [44]
How can you believe, which receive honour one of another, and
seek not the honour that comes from God only? [45] Do not think that I will accuse you to the Father:
there is one that accuses you, even Moses, in whom ye trust. [46] For
had you believed Moses, you would have believed me: for he wrote of me. [47] But
if ye believe not his writings, how shall you believe my words?
^so confusing.

If I had to guess if you believed not Moses,
how shall you believe My Words…I would say only through God removing the heart of stone, and giving you a new heart to know there is only One God the Father, and only one Lord Jesus Christ: 1 Corinthians 8:5-7 For even
if there are
so-called gods whether in heaven or on earth, as
indeed there are many gods and many lords, [6]
yet for us
there is only one God, the Father, from whom are all things, and we exist for Him;
and one Lord, Jesus Christ, by whom are all things, and we exist through Him. [7]
However,
not all people have this knowledge; but some, being accustomed to the idol until now, eat food as if it were sacrificed to an idol; and their conscience, being weak, is defiled.
If they had Moses and believed him not, how then shall they believe the Words of Christ? Considering His Words are Spirit…do we need to be given ears to hear (God opening the ears of those deaf) and eyes to see (God opening the eyes of the blind). If not then why 2 Corinthians 3:14-18 But their minds were blinded: for until this day
remains the same vail untaken away in the reading of the old testament; which vail is done away in Christ. [15] But
even unto this day, when Moses is read, the vail is upon their heart. [16] Nevertheless when it shall turn to the Lord,
the vail shall be taken away. [17] Now
the Lord is that Spirit: and
where the Spirit of the Lord is, there is liberty. [18] But we all, with open face beholding as in a glass the glory of the Lord, are changed
into the same image from glory to glory, even as
by the Spirit of the Lord.
Going back to: This is what stands out to me. Not being given a heart to know what? Or eyes to see what? Or ears to hear what?
With…even unto this day,
when Moses is read, the vail is upon their heart. Nevertheless when it shall turn to the Lord,
the vail shall be taken away. —to see and hear what?
