Jude 1:19
These are people who cause divisions [among God's people]; they follow their natural inclinations [i.e., worldly principles], for they do not have the Holy Spirit [in their lives].
1 Corinthians 2:14
Now the natural person [Note: Since this person is contrasted with the spiritual person of verse 15, it is taken here to mean the person without the Holy Spirit] does not receive the things [i.e., truths] revealed by the Holy Spirit of God, because they are [considered] foolishness to him. And he cannot understand them because they must be discerned by using spiritual judgment [i.e., judgment aided by the Holy Spirit].
Romans 8:9
But if the Spirit of God [truly] lives in your heart, you are not [being controlled] by the flesh, but by the Holy Spirit. But if any person does not have the Spirit of Christ [living in him], he does not belong to Christ.
James 3:15
This "wisdom" is not the kind that comes from [God] above, but is earthly, unspiritual and demonic [i.e., it is motivated by an evil spirit and not the Holy Spirit].
John 3:5-6
Jesus answered him, "Truly, truly, I tell you, a person cannot enter the kingdom of God unless he is born out of water and the Holy Spirit.
1 Corinthians 6:19
Or, do you not know that your [physical] body is a temple [i.e., sanctuary] for the Holy Spirit, who lives in you and who was given to you by God? You do not belong to yourselves,
Hebrews 10:25
We should not neglect our assembling together [as a church], as some people are in the habit of doing, but we should encourage one another [spiritually], and [do it] all the more [diligently] as you see the day [of judgment] coming closer.
