"Now we have received, not the spirit of the world, but the Spirit who is
from God, that we might know the things that have been freely given to us by
God." 1 Corinthians 2:12
 
Let us look more closely at the Holy Spirit's work in the life of Believers.
He is the giver of life:
It is Jesus who tells us in John 6:63 that it is the Spirit who gives life,
"It it the Spirit who gives life; the flesh profits nothing. The words that
I speak to you are spirit, and they are life."
 
And remember He said to Nicodemus in John 3:5,
"...Most assuredly, I say to you, unless one is born of water and the
Spirit, he cannot enter the kingdom of God."
 
Then in Romans 8:11 we see,
"But if the Spirit of Him who raised Jesus from the dead dwells in you, He
who raised Christ from the dead will also give life to your mortal bodies
through His Spirit who dwells in you."
 
He is our teacher:
We have John 14:26, a verse we all know well, Jesus tells the disciples,
"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 things that I
said to you."
 
Jesus speaking to His disciples in Luke 12:11-12,
"When you are brought before synagogue, rulers and authorities, do not
worry about how you will defend yourselves or what you will say, for the
Holy Spirit will teach you at that time what you should say." 
(Read Vs. 1-12)
 
The Apostle Paul in 1 Corinthians 2:13 says,
"These things we also speak, not in words which man's wisdom teachers but
which the Holy Spirit teaches, comparing spiritual things with spiritual."
 
The Holy Spirit leads and guides and of His leadership we see that--
He controls the movement of Believers:
"While Peter thought about the vision, the Spirit said to him, 'Behold,
three men are seeking you. So therefore, go down and go with them, doubting
nothing; for I have sent them." Acts 10:19-20
This is when the Spirit was leading him to minister to the Gentiles. (Read
Vs. 9-22)
 
He directs the selection of Christian leaders:
"As they ministered to the Lord and fasted, the Holy Spirit said, 'Now
separate to Me Barnabas and Saul for the work to which I have called them.'"
Acts 13:2
(I believer, however, there are some leaders who are only self appointed and
not of the Holy Spirit's selection. Here is a place where Christians need
the Holy Spirit's discernment.)
 
He chooses the areas where the work is to be done:
"Now when they had gone through Phrygia and the region of Galatia, they
were forbidden by the Holy Spirit to preach the word in Asia.
After they had come to Mysia, they tried to go into Bithynia, but the Spirit
did not permit them." Acts 16:6-7
Then we see in Vs. 8-10,
"So passing by Mysia, they came down to Troas.
And a vision appeared to Paul in the night. A man of Macedonia stood and
pleaded with him, saying, 'Come over to Macedonia and help us.'
Now after we had seen the vision, immediately we sought to go to Macedonia,
concluding that the Lord had called us to preach the gospel to them."
 
Obedience to the Holy Spirit's leading is a mark of sonship:
"For as many as are led by the Spirit of God, these are sons of God.
For you did not received the spirit of bondage again to fear, but you
received the Spirit of adoption by whom we cry out, 'Abba, Father.'"
Romans 8:14-15
 
Jesus said,
"...I am the way the truth, and the life.  No one comes to the Father except
through Me." John 14:6
 
The Bible is the revelation of Christ. Concealed in the Old Testament and
revealed in the New Testament. He is revealed by the Author, the Holy
Spirit. Jesus speaking to His disciples (and to us) in John 15:26,
"But when the Helper comes, whom I shall send to you from the Father, the
Spirit of truth who proceeds from the Father, He will testify of me."
 
I quote from "Experiencing God" by Henry and Richard Blackaby and
Clause King,
"You never discover truth; truth is revealed."
 
Thank You Father for The Holy Spirit for without Him and the revelation of
Your Son, we would still be in darkness and without hope. We love and
adore you Most Holy God! Amen
