14 Ye are my friends, if ye do whatsoever I command you.
15 Henceforth I call you not servants; for the servant knoweth not what his lord doeth: but I have called you friends; for all things that I have heard of my Father I have made known unto you.
Jesus also said this to His disciples (those who love and serve Him)...
Luke 14:25-27 (bold added)
25 And there went great multitudes with him: and he turned, and said unto them,
26 If any man come to me, and hate not his father, and mother, and wife, and children, and brethren, and sisters, yea, and his own life also, he cannot be my disciple.
27 And whosoever doth not bear his cross, and come after me, cannot be my disciple.
