Role of the Spirit

16 "I will ask the Father, and He will give you another 1Helper, that He may be with you forever;
17 that is 2the Spirit of truth, 3whom 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.
18 "I will not leave you as orphans; 4I will come to you.
