"If you love me, keep my commands. And I will ask the Father, and he will give you another advocate to help you and be with you forever – the Spirit of truth. The world cannot accept him, because it neither sees him nor knows him. But you know him, for he lives with you and will be in you.

...

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. Peace I leave with you; my peace I give you. I do not give to you as the world gives. Do not let your hearts be troubled and do not be afraid."

(John 14.15-17,26-27 NIV)

Let us not confuse which is cause and which is effect. My paraphrasing of the above.

Cause:

• Love Jesus
• Keep his commands

Effect:

• The Holy Spirit will be in me
• I will have peace
