Likewise the coming of the Holy Spirit, the Heavenly Dove, proved to the disciples that Christ had entered the heavenly sanctuary. He was seated at the right hand of God the Father, for His atoning work was finished. The advent of the Holy Spirit fulfilled Christ’s promise; and it also testified that God’s righteousness had been vindicated. The age of the Holy Spirit, which could not commence until Jesus was glorified, had now begun. - BILLY GRAHAM
