Spiritual things are spiritually discerned. God knows the heart (mind) of every soul: Who has Him, who does not—who desire to truly be saved (delivered from sin), and who do not. Only God knows the true spiritual state of the mind of every soul—we do not know it. But, God does reveal it to us through His Word via the Holy Spirit. Many say they are Jews but are not. Be not deceived.
“And the disciples came, and said unto him, Why speakest thou unto them in parables? He answered and said unto them, Because it is given unto you to know the mysteries of the kingdom of heaven, but to them it is not given. For whosoever hath, to him shall be given, and he shall have more abundance: but whosoever hath not, from him shall be taken away even that he hath. Therefore speak I to them in parables: because they seeing see not; and hearing they hear not, neither do they understand. And in them is fulfilled the prophecy of Esaias, which saith, By hearing ye shall hear, and shall not understand; And seeing ye shall see, and shall not perceive: For this people’s heart is waxed gross, And their ears are dull of hearing, And their eyes they have closed; Lest at any time they should see with their eyes, And hear with their ears, And should understand with their heart, And should be converted, and I should heal them. But blessed are your eyes, for they see: and your ears, for they hear. For verily I say unto you, That many prophets and righteous men have desired to see those things which ye see, and have not seen them; and to hear those things which ye hear, and have not heard them.”
Matthew 13:10-17 KJV
“But be ye doers of the word, and not hearers only, deceiving your own selves. For if any be a hearer of the word, and not a doer, he is like unto a man beholding his natural face in a glass: for he beholdeth himself, and goeth his way, and straightway forgetteth what manner of man he was. But whoso looketh into the perfect law of liberty, and continueth therein, he being not a forgetful hearer, but a doer of the work, this man shall be blessed in his deed.”
James 1:22-25 KJV
