John 14:26
26 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.

John 16:7-15
7 But I tell you the truth: It is for your good that I am going away. Unless I go away, the Counselor will not come to you; but if I go, I will send him to you.
8 When he comes, he will convict the world of guilt[a] 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.

12 "I have much more to say to you, more than you can now bear.
13 But when he, the Spirit of truth, comes, he will guide you into all truth. He will not speak on his own; he will speak only what he hears, and he will tell you what is yet to come.
14 He will bring glory to me by taking from what is mine and making it known to you.
15 All that belongs to the Father is mine. That is why I said the Spirit will take from what is mine and make it known to you.

Romans 8:14-17
14 because those who are led by the Spirit of God are sons of God.
15 For you did not receive a spirit that makes you a slave again to fear, but you received the Spirit of sonship. And by him we cry, "Abba, Father."
16 The Spirit himself testifies with our spirit that we are God's children.
17 Now if we are children, then we are heirs—heirs of God and co-heirs with Christ, if indeed we share in his sufferings in order that we may also share in his glory.

Ephesians 1:13-14
13 And you also were included in Christ when you heard the word of truth, the gospel of your salvation. Having believed, you were marked in him with a seal, the promised Holy Spirit,
14 who is a deposit guaranteeing our inheritance until the redemption of those who are God's possession—to the praise of his glory.
