Acts 1:1-5 NKJV

The former account I made, O Theophilus, of all that Jesus began both to do and teach, [2] until the day in which He was taken up, after He through the Holy Spirit had given commandments to the apostles whom He had chosen, [3] to whom He also presented Himself alive after His suffering by many infallible proofs, being seen by them during forty days and speaking of the things pertaining to the kingdom of God. [4] And being assembled together with them, He commanded them not to depart from Jerusalem, but to wait for the Promise of the Father, "which," He said, "you have heard from Me; [5] for John truly baptized with water, but you shall be baptized with the Holy Spirit not many days from now."

The Holy Spirit is The Helper
