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.
John 14:27 (NASB)
The Spirit of truth
I will ask the Father, and He will give you another Helper, that He may be with you forever;
that is the Spirit of truth, whom the world cannot receive, because it does not see Him or know Him, but you know Him because He abides with you and will be in you.
John 14:16-17 (NASB)
