In Jesus' farewell discourse to His disciples as we see in the Gospel of
John, Jesus shared many truths all of which we could delve into, but let
us go on with His word to us concerning the Holy Spirit.

Of the Holy Spirit He told us:
He will be a permanent resident:
"And I will ask the Father, and He will give you another Helper, that He
may be with you forever." John 14:16

He will teach and call to remembrance:
"...He will teach you all things and bring to your remembrance all that I
said to you." John 14:26

He will testify of Jesus (bears witness of Jesus):
"When the Helper comes, whom I will send to you from the Father, that is
the Spirit of truth, who proceeds from the Father, He will bear witness of
Me." John 15:26

He will convict:
"And He, when He comes, will convict the world concerning sin, and
righteousness, and judgment." John 16:8 (Vs. 8-11 expands on the
conviction of sin, righteousness and judgment.)

He will guide:
"...He will guide you into all the truth..." John 16:13

He will glorify Jesus:
"He shall glorify Me; for He shall take of Mine, and shall disclose it to
you." John 16:14

Just before our risen Savior left the earth He gave a command to the
disciples as we see in the following:
"And gathering them together, He (Jesus) commanded them not to leave
Jerusalem, but to wait for what the Father had promised, 'Which,' He
said, 'you heard from Me; for John baptized with water, but you shall be
baptized with the Holy Spirit not many days from now.'" Acts 1:4-5

He is the power:
"...you shall receive power when the Holy Spirit has come upon you..."
Acts 1:8
On the day of Pentecost the promised gift of the Holy Spirit was poured
out on the Church. That day that small band of Believers received power
at the out pouring of the Holy Spirit. The result we find in Acts Chapter 2.
It is in the power of the Holy Spirit that Peter took 'his stand with the
eleven' and preached the sermon 'that added that day about 3,000 soul.'
(Read all of Chapter 2 and share with all Believers Vs. 43,
"And everyone kept feeling a sense of awe..."

He is witness of our sonship:
"The Spirit Himself bears witness with our spirit that we are children of
God." Romans 8:16

He is our intercessor:
"...The Spirit also helps our weakness; for we do not know how to pray as
we should, but the Spirit Himself intercedes for us with groanings too deep
for words." Romans 8:26

Romans Chapter 8 reveals life in and through the Spirit and assures of
future glory and final victory.
"For all who are being led by the Spirit of God, these are sons of God."
Vs 14
"And if children, heirs also, heirs of God and fellow heirs with Christ..."
Vs 17

We can agree with those wonderful words in Vs 38-39:
"For I am convinced that neither death, now life, nor angels, nor
principalities, nor things present, nor things to come, nor powers, nor
height, now depth, nor any other created thing, shall be able to separate
us from the love of God, which is in Christ Jesus our Lord."

We know this to be true because:
".After listening to the message of truth, the gospel of our
salvation--having also believed, you were sealed in Him with the Holy
Spirit of promise, who is given as a pledge of our inheritance, with a view
to the redemption of God's own possession, to the praise of His glory."
Ephesians 1:13-14
Hallelujah and Amen!
