Rocketman123, actually according to some verses in the Bible, Jesus did say his disciples (at the least ones who were his faithful apostles) are no part of the world (though physically in the world). John 17:6 first part, 9, 11 first part, and 14 - 16 (NKJV) say: "I have manifested Your name to the men whom You have given Me out of the world. ... I pray for them. I do not pray for the world, but for those whom You have given Me, for they are Yours. ... Now I am no longer in the world, but these are in the world, and I come to You. ... I have given them, Your word; and the world has hated them because they are not of the world, just as I am not of the world. I do not pray that You should take them out of the world, but that You should keep them from the evil one. They are not of the world, just as I am not of the world."
Verses 14 and 16 (NWT of 1984) says "... no part of the world ..." instead of "... not of the world ...".
