1 Corinthians 3:16 Don't you know that you yourselves are God's temple and that God's Spirit lives in you?
1 Corinthians 2:9-12
9 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.
11 The Spirit searches all things, even the deep things of God.
For who among men knows the thoughts of a man except the man's spirit within him?
In the same way no one knows the thoughts of God except the Spirit of God.
12 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.
Romans 8:11 And if the Spirit of him who raised Jesus from the dead is living in you, he who raised Christ from the dead will also give life to your mortal bodies through his Spirit, who lives in you.
John 15:15 I no longer call you servants, because a servant does not know his master's business. Instead, I have called you friends, for everything that I learned from my Father I have made known to you.
John 17:22-23
22 I have given them the glory that you gave me, that they may be one as we are one:
23 I in them and you in me. May they be brought to complete unity to let the world know that you sent me and have loved them even as you have loved me.
