John 14:16; John 14:26; John 16:26; John 16:7

16 And I will ask the Father, and he will give you another advocate to help you and be with you forever—
26 But the Advocate, 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.
26 In that day you will ask in my name. I am not saying that I will ask the Father on your behalf.
7 But very truly I tell you, it is for your good that I am going away. Unless I go away, the Advocate will not come to you; but if I go, I will send him to you.
