John 14:25-27  NAS

"These things I have spoken to you while abiding with you.  But the Helper, the Holy Spirit, whom the Father will send in My name, He will teach you all things, and bring to your remembrance all that I said to you.  Peace I leave with you; My peace I give to you; not as the world gives do I give to you.  Do not let your heart be troubled, nor let it be fearful.
