Chapter and verse so I can look it up. Joel speaks twice of the Spirit in terms of future prophecy.
In the meantime...
(But this spake he of the Spirit, which they that believe on him should receive: for the Holy Ghost was not yet given; because that Jesus was not yet glorified.)
(Joh 7:39)
Here you are:
The promise of the seal of the Holy Spirit
Joel 2:28 "It will come about after this That I will pour out My Spirit on all mankind; And your sons and daughters will prophesy, Your old men will dream dreams, Your young men will see visions. 29"Even on the male and female servants I will pour out My Spirit in those days.…
Eph 1:13 In Him, you also, after listening to the message of truth, the gospel of your salvation-- having also believed, you were sealed in Him with the Holy Spirit of PROMISE, 14who is GIVEN as a pledge...
1Cor 12:3 Therefore I make known to you that no one speaking by the Spirit of God says, "Jesus is accursed"; and no one can say, "Jesus is Lord," except by the Holy Spirit.
So the moment you believed "Jesus is Lord", you were {sealed in Him with the OT promise of the HS} given by the Father to be proclaimed by His Prophet Joel.
I rest my case, your witness.....
