Seventh-day Adventist Church
It's in the Bible, John 14:16-17, TLB. "He is the Holy Spirit, the Spirit who leads into all truth. The world at large cannot receive Him, for it isn't looking for Him and doesn't recognize Him. But you do, for He lives with you now and some day shall be in you."
Receiving the Holy Spirit is referred to as the new birth. It's in the Bible, John 3:5-7, TLB. "Jesus replied, 'What I am telling you so earnestly is this: Unless one is born of water and the Spirit, he cannot enter the Kingdom of God. Men can only reproduce human life, but the Holy Spirit gives new life from heaven; so don't be surprised at My statement that you must be born again!"
To receive the Holy Spirit, just ask then obey the Holy Spirit's leading. It's in the Bible, Luke 11:13, TLB. "And if even sinful persons like yourselves give children what they need, don't you realize that your heavenly Father will do at least as much, and give the Holy Spirit to those who ask for Him?" Acts 5:32, NIV says, "We are witnesses of these things and so is the Holy Spirit, whom God has given to those who obey Him."
The Holy Spirit is part of the Godhead. It's in the Bible, Acts 5:3,4, NIV. "They Peter said, 'Ananias, how is it that Satan has so filled your heart that you have lied to the Holy Spirit and have kept for yourself some of the money you received for the land? Didn't it belong to you before it was sold? And after it was sold, wasn't the money at your disposal? What made you think of doing such a thing? You have not lied to men but to God.'"
The Holy Spirit was active in creation. It's in the Bible, Genesis 1:2 NKJV. "The earth was without form, and void; and darkness wason the face of the deep. And the Spirit of God was hovering over the face of the waters."
The Holy Spirit is a personal being. It's in the Bible, Ephesians 4:30, NKJV "And do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption."
The Holy Spirit is God living in and among those who believe. It's in the Bible, Matthew 18:19-20, TLB. "I also tell you this—if two of you agree down here on earth concerning anything you ask for, My Father in heaven will do it for you. For where two or three gather together because they are Mine, I will be right there among them."
The Holy Spirit gives comfort. It's in the Bible, Acts 9:31, NKJV. "Then the churches throughout all Judea, Galilee, and Samaria had peace and were edified. And walking in the fear of the Lord and in the comfort of the Holy Spirit, they were multiplied."
The Holy Spirit is present in times of hardship. It's in the Bible, Matthew 10:19-20, TLB. "When you are arrested, don't worry about what to say at your trial, for you will be given the right words at the right time. For it won't be you doing the talking—it will be the Spirit of your heavenly Father speaking through you!"
The Holy Spirit helps us worship God. It's in the Bible, John 4:23-24, NIV. "Yet a time is coming and has now come when the true worshipers will worship the Father in spirit and truth, for they are the kind of worshipers the Father seeks. God is spirit, and His worshipers must worship in spirit and in truth."
The Holy Spirit helps with our prayers. It's in the Bible, Romans 8:26-27, 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. And he who searches our hearts knows the mind of the Spirit, because the Spirit intercedes for the saints in accordance with God's will."
The Holy Spirit gives the ability to talk about spiritual things with power. It's in the Bible, Acts 1:8, TLB. "But when the Holy Spirit has come upon you, you will receive power to testify about Me with great effect, to the people in Jerusalem, throughout Judea, in Samaria, and to the end of the earth, about my death and resurrection."
