Charles Spurgeon Commentary Acts 2:33

"Being therefore by the right hand of God exalted, and having received of the Father the promise of the Holy Spirit, he hath poured forth this, which ye see and hear." — Acts 2:33 (ASV)

Therefore being by the right hand of God exalted, and having received from the Father the promise of the Holy Ghost, he has shed forth this, which you now see and hear.

"This, which is a mystery to you, is the result of Christ's exaltation at the right hand of His Father."

Therefore being by the right hand of God exalted, and having received of the Father the promise of the Holy Ghost, he hath shed forth this, which ye now see and hear.

Was not that enough to convince them? They saw and they heard the proofs of the working of the Spirit among them, and Peter told them that "this" was the gift of Christ, who had ascended up on high. It must have been a very striking thing, to have been there, and to have heard and seen these tokens of God setting his seal to the work of Jesus.
