What happens when we work with the Spirit
We will receive power
The greater part of the Old Testament passages which refer to the Spirit of God have to do with gifts and powers conferred by the Spirit for service in the ongoing of the kingdom of God.
The children of Israel cried unto Yahweh and He raised up a savior for them, Othniel, the son of Kenaz: “And the Spirit of Yahweh came upon him, and he judged Israel” (Jdg_3:10). So also Gideon (Jdg_6:34): “The Spirit of Yahweh came upon (literally, clothed itself with) Gideon.” In Jdg_11:29 “the spirit of Yahweh came upon Jephthah”; and in Jdg_13:25 “the Spirit of Yahweh began to move” Samson. In Jdg_14:6 “the Spirit of Yahweh came mightily upon him.” In 1Sa_16:14 we read “the Spirit of Yahweh departed from Saul, and an evil spirit from Yahweh troubled him.” In all this class of passages, the Spirit imparts special endowments of power.

It is the Holy Spirit working in the lives of these individuals and not their own capabilities that resulted in their ability to do the special task.
(Zec 4:6 NIV) So he said to me, “This is the word of the LORD to Zerubbabel: ‘Not by might nor by power, but by my Spirit,’ says the LORD Almighty.
Likewise in the New Testament, the receiving of the Holy Spirit is accompanied by power.
(Luke 1:35 NIV) The angel answered, “The Holy Spirit will come upon you, and the power of the Most High will overshadow you. So the holy one to be born will be called the Son of God.
(Luke 24:49 NIV) I am going to send you what my Father has promised; but stay in the city until you have been clothed with power from on high.”
The Spirit helps us in our weakness
(Rom 8:26 NIV) In the same way, the Spirit helps us in our weakness. We do not know what we ought to pray for, but the Spirit himself intercedes for us with groans that words cannot express.
The Spirit reveals the things of God to us
(1 Cor 2:12 NIV) We have not received the spirit of the world but the Spirit who is from God, that we may understand what God has freely given us.
(1 Cor 2:9-10 NIV) However, as it is written: “No eye has seen, no ear has heard, no mind has conceived what God has prepared for those who love him”– {10} but God has revealed it to us by his Spirit. The Spirit searches all things, even the deep things of God.
(John 16:14 NIV) He will bring glory to me by taking from what is mine and making it known to you.
(John 14:26 NIV) But the Counselor, the Holy Spirit, whom the Father will send in my name, will teach you all things and will remind you of everything I have said to you.

The Spirit convicts us of sin
John 16:8-11 (NIV) When he comes, he will convict the world of guilt in regard to sin and righteousness and judgment: 9 in regard to sin, because men do not believe in me; 10 in regard to righteousness, because I am going to the Father, where you can see me no longer; 11 and in regard to judgment, because the prince of this world now stands condemned.
(Isa 11:2-3 NIV) The Spirit of the LORD will rest on him– the Spirit of wisdom and of understanding, the Spirit of counsel and of power, the Spirit of knowledge and of the fear of the LORD– {3} and he will delight in the fear of the LORD. He will not judge by what he sees with his eyes, or decide by what he hears with his ears;
The Spirit enables us to speak in the prophetic
The most distinctive and important manifestation of the Spirit’s activity in the Old Testament was in the sphere of prophecy. The prophet was especially distinguished from others as the man who possessed the Spirit of God (Hos_9:7).
(Hosea 9:7 NRSV) The days of punishment have come, the days of recompense have come; Israel cries, “The prophet is a fool, the man of the spirit is mad!” Because of your great iniquity, your hostility is great.
(Acts 2:17-18 NIV) “‘In the last days, God says, I will pour out my Spirit on all people. Your sons and daughters will prophesy, your young men will see visions, your old men will dream dreams. {18} Even on my servants, both men and women, I will pour out my Spirit in those days, and they will prophesy.
(1 Sam 10:9-10 NIV) As Saul turned to leave Samuel, God changed Saul’s heart, and all these signs were fulfilled that day. {10} When they arrived at Gibeah, a procession of prophets met him; the Spirit of God came upon him in power, and he joined in their prophesying.
(2 Pet 1:21 NIV) For prophecy never had its origin in the will of man, but men spoke from God as they were carried along by the Holy Spirit.
The Spirit helps us to proclaim God’s word
(2 Chr 24:20 NIV) Then the Spirit of God came upon Zechariah son of Jehoiada the priest. He stood before the people and said, “This is what God says: ‘Why do you disobey the Lord’s commands? You will not prosper. Because you have forsaken the LORD, he has forsaken you.'”
(1 Cor 2:4 NIV) My message and my preaching were not with wise and persuasive words, but with a demonstration of the Spirit’s power,
The Spirit helps in our evangelistic efforts.
(John 15:26 NIV) “When the Counselor comes, whom I will send to you from the Father, the Spirit of truth who goes out from the Father, he will testify about me.
The Spirit does not just help us to testify, He Himself testifies about Jesus.
(Rom 8:14 NIV) because those who are led by the Spirit of God are sons of God.
The Spirit helps us in our battles
(Isa 59:19 KJV) So shall they fear the name of the LORD from the west, and his glory from the rising of the sun. When the enemy shall come in like a flood, the Spirit of the LORD shall lift up a standard against him.
