Hatred is a good indicator as to where you are spiritually! Most would tend to immediately think all hatred is bad and a sign of being lost spiritually, but if our hatred is towards evil and falsehood, it is actually a good indicator of our present spirituality!
The Bad Hatred
The bad hatred some have towards the righteous and God’s truth reflects such a person is traveling on the road to eternal torment, with the multitudes. 
The Bible is explicitly clear about this form of murder:
Anyone who hates his brother is a murderer, and you know that no murderer has eternal life in him. (1 John 3:15)
Since NO murderer has eternal life and hatred towards another is murder (1 John 3:15), then such hatred proves such a person is not a Christian (while he has such hatred). Before coming to initial salvation (getting born again), a general tendency of all of us is, we were hating others (Titus 3:5), which substantiates 1 John 3:15. The context of 1 John 3:15 tells us more, as it focuses on Cain and Abel mentioned in Genesis 4:
Do not be like Cain, who belonged to the evil one and murdered his brother. And why did he murder him? Because his own actions were evil and his brother’s were righteous. Do not be surprised, my brothers, if the world hates you. (1 John 3:12,13)
Cain hated his own natural brother, because he was doing the right things, just as the world will hate Christians today. Cain was a perfect example of the world, which unjustly persecutes the righteous for their obedience to God. He even murdered righteous Abel over that.
The Good Hatred
On the other hand, if you are spiritually healthy, you can’t just sit back and observe all the lies and evil flooding throughout our world without being stirred! Souls are perishing and something needs to be done. Hence, we read of a godly hatred, which should be present in one’s life:
A righteous man hates falsehood …. (Prov 13:5)
I hate and despise falsehood, But I love Your law. (Psa 119:163)
Hate evil, you who love the LORD … (Psa 97:10)
The fear of the LORD is to hate evil … (Prov 8:13)
… Abhor what is evil …. (Rom 12:9)
It is the righteous who hate falsehood (false doctrine), based on the criterion of the Bible. A prime example of hating falsehood is hating once saved always saved. Dear reader, if you profess to be a Christian now, does that describe you now? Furthermore, do you hate sin? Sin is not only poison, it is deadly spiritual poison. It will kill the Christian and bring him to spiritual death. Sin is to be resisted and avoided and never toyed with. Jesus taught sin will drag you to hell (Mark 9:43-48). That hell warning, according to the context, was given to those who had already been saved (v.35)! There are also other such hell warnings to the saved found in Scripture, all of which would be impossible if eternal security was truth!
Hatred Is A Spiritual Litmus Paper
In conclusion, remember that hatred is a type of spiritual litmus paper reflecting one’s heart, 
if it is presently alive or dead. To be halfhearted towards dangerous false doctrine and/or sin is to be lukewarm, which brings us to another hell warning given to Christians (Rev.3:15,16):
I know your deeds, that you are neither cold nor hot. I wish you were either one or the other! So, because you are lukewarm–neither hot nor cold–I am about to spit you out of my mouth.
QUESTION: Do you HATE SIN AND FALSE DOCTRINE now, at this time? Note, the question was not if you ever hated evil, but do you HATE it NOW? If not, repent, draw near to God and strengthen yourself spiritually. You need that type of hatred, while not having any of the bad type of hatred mentioned formerly!
