Holy Spirit

Ezekiel 36:26-27

“Moreover, I will give you a new heart and put a new spirit within you; and I will remove the heart of stone from your flesh and give you a heart of flesh. “I will put My Spirit within you and cause you to walk in My statutes, and you will be careful to observe My ordinances.”

Joel 2:28

“It will come about after this That I will pour out My Spirit on all mankind; And your sons and daughters will prophesy, Your old men will dream dreams, Your young men will see visions. “Even on the male and female servants I will pour out My Spirit in those days.”

John 14:26

“But the Helper, the Holy Spirit, whom the Father will send in my name, he will teach you all things and bring to your remembrance all that I have said to you.”

Romans 8:26-27
“Likewise the Spirit helps us in our weakness. For we do not know what to pray for as we ought, but the Spirit himself intercedes for us with groanings too deep for words.  And he who searches hearts knows what is the mind of the Spirit, because the Spirit intercedes for the saints according to the will of God.”
