Just leaving this one here.. (Pope Francis), page-88

New International Version 8 But you will receive power when the Holy Spirit comes on you;

This is what would be coming to them -> John 14:23 - Jesus answered and said unto him, If a man love me, he will keep my words: and my Father will love him, and we will come unto him, and make our abode with him.


God being the Holy Spirit which was in Jesus and Jesus coming with the aid and power of the Holy Spirit (Father).

14:10 - Believest thou not that I am in the Father, and the Father in me? the words that I speak unto you I speak not of myself: but the Father that dwelleth in me, he doeth the works.
3:34 - For he whom God hath sent speaketh the words of God: for God giveth not the Spirit by measure unto him.

God gave of himself without measure, as a father would do.
