Why don't People believe they will prophecy ?

[Joelel]

Most will agree what Isa.wrore was talking about the pouring out of the Holy Ghost.Isa.28:11: For with stammering lips and another tongue will he speak to this people.12: 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.

Then Paul writting about the gift of tongues referred to Isa.1 Cor. 14:21: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.22: Wherefore tongues 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.

Paul said here very clearly, with the lips of believers who speak other tongues God will speak to unbelievers and it is a sign to the unbeliever and after all of that they still will not hear God, says the Lord. This is what took place on the Day of Pentecost. Therefore the tongues they spoke in on the day of Pentecost was the gift of tongues
