Hating evil is one piece of evidence that one is saved. Hating evil only in others is evidence that we are not saved or that we are misguided Christians.
Proverbs 8:13: The fear of the LORD is to hate evil: pride, and arrogancy, and the evil way, and the froward mouth, do I hate.
God is able to hate sin and yet love the sinner. Christians should do those same things. They are not easy. We should love the things that God loves and hate the things that He hates.
If we hate the sins of others but not our own, our hatred is misdirected. It needs to be directed at our own sin MORE than at the sin of others. If we are right with God we will know a whole lot more about our own sin than we know about the sin of others and there will be more of our own sin to hate. Hating our own sin will do us more good than hating the sin of others. If that is our case, we are close to the position of Paul the Apostle.
1 Timothy 1:15: This is a faithful saying, and worthy of all acceptation, that Christ Jesus came into the world to save sinners; of whom I am chief.
Romans 7:24-25: O wretched man that I am! who shall deliver me from the body of this death? 25 I thank God through Jesus Christ our Lord. So then with the mind I myself serve the law of God; but with the flesh the law of sin.
We should ALL feel like we are the chief of sinners. We should be aware of our inward sins as well as our outward ones. We cannot know that the inward sins of others are as depraved as our own. Neither can we know for certain when the sins of others have been forgiven by God. Even though we might continue to hate sins that God has forgiven, it should be easier to love someone that God has forgiven.
Romans 14:4: Who art thou that judgest another man*s servant? to his own master he standeth or falleth. Yea, he shall be holden up: for God is able to make him stand.
John 8:7: So when they continued asking him, he lifted up himself, and said unto them, He that is without sin among you, let him first cast a stone at her.
If we have unforgiven sin in our life our hatred of the sins of others will miss the mark.
Matthew 7:3-5: And why beholdest thou the mote that is in thy brother*s eye, but considerest not the beam that is in thine own eye? 4 Or how wilt thou say to thy brother, Let me pull out the mote out of thine eye; and, behold, a beam is in thine own eye? 5 Thou hypocrite, first cast out the beam out of thine own eye; and then shalt thou see clearly to cast out the mote out of thy brother*s eye.
The sins of others against God are more significant than they are against me. I did not create them and they do not owe me what they owe God.
Psalms 51:4: Against thee, thee only, have I sinned, and done this evil in thy sight: that thou mightest be justified when thou speakest, and be clear when thou judgest.
Romans 12:3: For I say, through the grace given unto me, to every man that is among you, not to think of himself more highly than he ought to think; but to think soberly, according as God hath dealt to every man the measure of faith.
Philippians 2:3: Let nothing be done through strife or vainglory; but in lowliness of mind let each esteem other better than themselves.
James 2:1: My brethren, have not the faith of our Lord Jesus Christ, the Lord of glory, with respect of persons.
The one we should have the most knowledge of and the least respect for is ourself.
