Let me put it like this and you can discern...
The original command in Covenant Israel:
Leviticus 19:17-18 (KJV)
17 Thou shalt not hate thy brother (member of the same tribe) in thine heart: thou shalt in any wise rebuke thy neighbor (member of another tribe), and not suffer sin upon him.
18 Thou shalt not avenge, nor bear any grudge against the children of thy people (member of ANY of the 12 tribes), but thou shalt love thy neighbour (member of another tribe) as thyself: I
am the LORD.
Now, when you see these words..."I
am the LORD" then "you" need to pay close attention and do not sin against the LORD because He STILL is a jealous God. The same when you see three "woe's" in a passage. Pay attention!
So, in accordance with the expressed will of God the command is to love brethren ONLY.
There is no redundancy in this next passage:
1 John 2:15 (KJV)
15 Love not the world (unsaved people), neither the things
that are in the world. If any man love the world, the love of the Father is not in him.
The translated from Greek here is "world" and the Greek word is "kosmos" which is defined by Strong as...
(kosmos from base of komizo); orderly
arrangement, i.e.
decoration; by implication the
world (in a wide or narrow sense,
including its inhabitant, literal or figurative [moral])
True brethren are commanded to love brethren ONLY.
God hates the non-elect people that He will never save. He only bears with them because of the lamb slain from before the foundation of the world and the Elect, those whose names are in the book of life of the lamb slain....
Here's more:
Psalm 5:5 (KJV)
5 The foolish shall not stand in thy sight: thou hatest all
workers of iniquity.
Psalm 11:5 (KJV)
5 The LORD trieth the righteous: but the
wicked and
him that loveth violence his soul hateth.
Do you know what a personal pronoun is?
"workers, wicked, him" are personal pronouns meaning the PERSON.
God hates (unatoned) sin AND (unatoned) sinner.
And He doesn't love them today, save them tomorrow and now He loves them. God does not change. His Love is Immutable.
