[Jhn 15:15 NIV] (15) I no longer call you servants, because a servant does not know his master's business. Instead, I have called you friends, for everything that I learned from my Father I have made known to you.
How is that different from God's servants, the prophets?
[Amo 3:7 ASV] (7) Surely the Lord Jehovah will do nothing, except he reveal his secret unto his servants the prophets.
[Mat 13:17 DBY] (17) for verily I say unto you, that many prophets and righteous men have desired to see the things which ye behold and did not see them, and to hear the things which ye hear and did not hear them.
