I'll try to explain with an example.
Assume the understanding of the Bible is your key to unlock the door of the prison.
What happens if we assume that some people could not believe the testimony of God because God binded them?
- John 12:38 That the saying of Esaias the prophet might be fulfilled, which he spake, Lord, who hath believed our report? and to whom hath the arm of the Lord been revealed? 39 Therefore they could not believe, because that Esaias said again, 40 He hath blinded their eyes, and hardened their heart; that they should not see with their eyes, nor understand with their heart, and be converted, and I should heal them.
If one is OUTSIDE the veil..how can ONE SEE?... for MANY are called But Few are Chosen, I see this as the Jews ..like the disciples...Those of their DAY to were invited to the wedding feast , but only those CLOTHED were permitted.
Saul Himself was Blind, and it was THE PRIDE of The LAW which caused it ,having his scales removed
Job 41:15 [His] scales [are his] pride, shut up together [as with] a close seal.
Again , they believe the FORM not the reality Rom 2:19...
Paul himself, later come to Understand what is Known as the Mystery (of) the ages .....Christ revealed from within.
HIS door will always remained Locked for those outside the veil while they remain in the Old C ,
Luk 13:24 Strive to enter in at the strait gate: for many, I say unto you, will seek to enter in, and shall not be able.
Luk 13:25 When once the master of the house is risen up, and hath shut to the door, and ye begin to stand without, and to knock at the door, saying, Lord, Lord, open unto us; and he shall answer and say unto you, I know you not whence ye are:
Luk 13:27 But he shall say, I tell you, I know you not whence ye are; depart from me, all [ye]
workers of iniquity. 9 by the HANDS of law)
By returning to LAW we fall from Grace, AS some did ...
Gal 5:4 Christ is become of no effect unto you, whosoever of you are justified by the law; ye are
fallen from grace we are to BELIEVE in HIM who Overcome FOR US!
Rev 3:17 Because thou sayest, I am rich, and increased with goods, and have need of nothing; and knowest not that thou art wretched, and miserable, and poor, and blind, and naked:
Rev 3:18 I counsel thee to buy of me gold tried in the fire, that thou mayest be rich; and white raiment, that thou mayest be clothed, and [that] the shame of thy nakedness do not appear;
and anoint thine eyes with eyesalve, that thou mayest see. Rev 3:19 As many as I love, I rebuke and chasten: be zealous therefore, and repent. Rev 3:20 Behold, I stand at the door, and knock: if any man
hear my voice, and
open the door, I will come in to him, and will sup with him, and he with me. Rev 3:21 To him that
overcometh will I grant to sit with me in my throne, even as I also overcame, and am set down with my Father in his throne.
Rev 3:22 He that hath an ear, let him hear what the Spirit saith unto the churches
