For what man knoweth the things of a man, save the spirit of man which is in him? even so the things of God knoweth no man, but the Spirit of God.
For anyone who speaks in a tongue does not speak to people but to God. Indeed, no one understands them; they utter mysteries by the Spirit.
I would suggest no such thing as "sign gifts" as least to those who walk by faith (the unseen eternal) Sign curses that confirms men refuse to hear prophecy, yes.
Prophecy (God's word ) is
of God (coming from) not towards or
to God. In the end of the matter
to God must mean of or coming from God to or towards the people. And the word tongue is always interpreted as language that used to give a person faith or clear direction.
No secret languages .Its why he has given us parables they hide the meaning and not hide the conversation. When we prophecy we utter his mysteries that he makes known . Hiding them from those who do not have ears hear.
Turning the sign of rebellion upside down makes prophecy without effect. (yet they would not hear)
It is as David under the inspiration of the Holy Spirit informs us in the Psalms . If they destroy the foundation of His doctrines like the tongues law . What will His children do...? How will they reconcile the law given to them in 1 Corinthians 14 ? Do we remove chapter 28 from the book of Isaiah. Or compare the foundation (Isiah 28) to the fulfillment (1 Corinthians 14)?
For with stammering lips and another tongue will he speak to this people.To whom he said, This is the rest wherewith ye may cause the weary to rest; and this is the refreshing: yet they would not hear. But the word of the Lord was unto them precept upon precept, precept upon precept; line upon line, line upon line; here a little, and there a little; that they might go, and fall backward, and be broken, and snared, and taken.Wherefore hear the word of the Lord, ye scornful men, that rule this people which is in Jerusalem.Because ye have said, We have made a covenant with death, and with hell are we at agreement; when the overflowing scourge shall pass through, it shall not come unto us: for we have made lies our refuge, and under falsehood have we hid ourselves: Isaiah 28:11-15
Why did God mock Jews using stammering lips the in that way? Find that out an the sign become apparent.
In the law it is written, With men of other tongues and other lips will I speak unto this people; and yet for all that will they not hear me, saith the Lord. Wherefore t
ongues are for
a sign, "not to them
that believe", but
to them that believe not: but prophesying serveth not for them that believe not, but for them which believe.1 Corinthians 14:21-22
To me the real mystery is how did a sign that confirms un-belief (no faith) get turned around and made into a gift? Who is behind that kind of work?
What kind of gift confirms a person refuses to hear God?
