no more do I call you servants, because the servant hath not known what his lord doth, and you I have called friends, because all things that I heard from my Father, I did make known to you.
John 15:13 greater love than this hath no one, that any one his life may lay down for his friends;

John 15:15 no more do I call you servants, because the servant hath not known what his lord doth, and you I have called friends, because all things that I heard from my Father, I did make known to you.
John 15:16 `Ye did not choose out me, but I chose out you, and did appoint you, that ye might go away, and might bear fruit, and your fruit might remain, that whatever ye may ask of the Father in my name, He may give you.
John 15:17 `These things I command you, that ye love one another;
The verse centers on "all things", "called", "servants", "hath", "known", "lord", and "doth". It is saying that the verse draws attention to "all things" and "called", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 14's "ye are my friends if ye may..." into verse 16's "Ye did not choose out me but...", so "all things" and "called" belong inside that flow. In John context, the local focus is the identity of Jesus, new birth, eternal life, and belief and unbelief.
A plain takeaway is to answer the verse's own emphasis on "all things" and "called" with trust shaped by these words, not by a vague optimism outside the passage.
