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.
When read or study or hear Gods word. The Spirit brings it to our minds and heart and we remember it. The Spirit is our teacher.
Jesus gives us peace. It is not the kind of no conflict or trouble. It is an inner peace. The Peace that comes from fellowship with Jesus. He is Peace Himself.
