John 15:15
“I no longer call you servants, because a servant does not know what his master is doing. But I call you friends, because I have made known to you everything I heard from My Father.”

Jesus described for His followers what He came to do. He came to build a relationship with people. He came to take away enmity, to take away the strife, to take away the isolation that existed between God and man. Once He bridged that, once He overcame that, He said, “I will call you friends.”
