Mark 1:6-8

It is impossible to internalize the teachings of  Scripture without the Holy Spirit. He takes the teachings of Christ, and the Testaments written through men under His inspiration, and explains  them to us. He is our teacher and without Him there would be no permanent change. The Holy Spirit matures us, precept by precept, into the image of His Son. Without Him we will read the Bible without comprehending the context. He brings the Gospels to life by abiding in us...completing God’s plan of redemption for those who by faith believe in the salvation provided in Jesus Christ. 

The prediction that Christ will baptize you with the Holy Spirit appears in each Gospel. The water is a physical representation of the future life in the Spirit that people who followed the Messiah would have. Presumably the Day of Pentecost marked the fulfillment of this promise.

Romans 5: Therefore, having been justified by faith, we have peace with God through our Lord Jesus Christ, ² through whom also we have access by faith into this grace in which we stand, and rejoice in hope of the glory of God. ³ And not only that, but we also glory in tribulations, knowing that tribulation produces perseverance; ⁴ and perseverance, character; and character, hope. ⁵ Now hope does not disappoint, because the love of God has been poured out in our hearts by the Holy Spirit who was given to us. 

Mark 1:6-8

⁶ Now John was clothed with camel’s hair and with a leather belt around his waist, and he ate locusts and wild honey. ⁷ And he preached, saying, “There comes One after me who is mightier than I, whose sandal strap I am not worthy to stoop down and loose. ⁸ I indeed baptized you with water, but He will baptize you with the Holy Spirit.”
