Biblical Concept: Holy Spirit and Biblical-Christ-Believers
What the Holy Spirit does for Biblical-Christ-Believers : Regenerated, Renewed, Indwelled, Sanctified, Sealed, Baptized, Gifted, Helper, Filling, Fellowship, Leading, Walking, Fruits, Confirms, Teaching, and Worship. (What a cool list! But, also a humbling list. A needy list for Believers.)
Here are the Bible references:
Renewed - Titus 3:5 He saved us, not on the basis of deeds which we have done in righteousness, but according to His mercy, by the washing of regeneration and renewing by the Holy Spirit,
Sanctified - 2 Thessalonians 2:13 But we should always give thanks to God for you, brethren beloved by the Lord, because God has chosen you from the beginning for salvation through sanctification by the Spirit and faith in the truth.
Baptized - 1 Corinthians 12:12 For even as the body is one and yet has many members, and all the members of the body, though they are many, are one body, so also is Christ. 13 For by one Spirit we were all baptized into one body, whether Jews or Greeks, whether slaves or free, and we were all made to drink of one Spirit.
Helper - John 14:16 "And I will ask the Father, and He will give you another Helper, that He may be with you forever; 17 that is the Spirit of truth, whom the world cannot receive, because it does not behold Him or know Him, but you know Him because He abides with you, and will be in you.
Confirms - Romans 8:14 For all who are being led by the Spirit of God, these are sons of God. 15 For you have not received a spirit of slavery leading to fear again, but you have received a spirit of adoption as sons by which we cry out, "Abba! Father!" 16 The Spirit Himself bears witness with our spirit that we are children of God,
Teaching - 1 Corinthians 2:12 Now we have received, not the spirit of the world, but the Spirit who is from God, that we might know the things freely given to us by God, 13 which things we also speak, not in words taught by human wisdom, but in those taught by the Spirit, combining spiritual thoughts with spiritual words.
Some ways for believers to mess up the Spirit relationship:
Quench - 1 Thessalonians 5:19 Do not quench the Spirit;
Grieve - Ephesians 4:30 And do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption.
Insult - Hebrews 10:29 How much severer punishment do you think he will deserve who has trampled under foot the Son of God, and has regarded as unclean the blood of the covenant by which he was sanctified, and has insulted the Spirit of grace?
