SIN, or yielding to Satan, breeds contempt.
In regard to human relationships, we see this first with Cain and Abel, and it has continued on throughout history until our day.
1 John 3
11For this is the message that ye heard from the beginning, that we should love one another.
12Not as Cain,
who was of that wicked one, and slew his brother. And wherefore slew he him? Because his own works were evil, and his brother's righteous.
13Marvel not, my brethren, if the world hate you.
14We know that we have passed from death unto life, because we love the brethren. He that loveth not
his brother abideth in death.
15Whosoever hateth his brother is a murderer: and ye know that no murderer hath eternal life abiding in him.
I can honestly (and sadly) say that the world hates me, and solely because of my walk with Christ. In other words, it's really Christ that they hate, and not me. I stopped marveling at that a long, long time ago. It is what it is.
John 15
18If the world hate you, ye know that it hated me before
it hated you.
19If ye were of the world, the world would love his own: but because ye are not of the world, but I have chosen you out of the world, therefore the world hateth you.
20Remember the word that I said unto you, The servant is not greater than his lord. If they have persecuted me, they will also persecute you; if they have kept my saying, they will keep yours also.
21But all these things will they do unto you for my name's sake, because they know not him that sent me.
22If I had not come and spoken unto them, they had not had sin: but now they have no cloke for their sin.
23He that hateth me hateth my Father also.
24If I had not done among them the works which none other man did, they had not had sin: but now have they both seen and hated both me and my Father.
25But
this cometh to pass, that the word might be fulfilled that is written in their law, They hated me without a cause.
Just speak the truth of God's word to the average person, and the average "Christian", and you'll be treated with contempt because it is ultimately contempt for God that leads to contempt for others. Again, it is what it is, and there's a very real day of judgment coming when Christ himself will deal with the evildoers. It won't be pretty, but it will be just.
Matthew 5
21Ye have heard that it was said by them of old time, Thou shalt not kill; and whosoever shall kill shall be in danger of the judgment:
22But I say unto you, That whosoever is angry with his brother without a cause shall be in danger of the judgment: and whosoever shall say to his brother, Raca, shall be in danger of the council: but whosoever shall say, Thou fool, shall be in danger of hell fire.
23Therefore if thou bring thy gift to the altar, and there rememberest that thy brother hath ought against thee;
24Leave there thy gift before the altar, and go thy way; first be reconciled to thy brother, and then come and offer thy gift.
25Agree with thine adversary quickly, whiles thou art in the way with him; lest at any time the adversary deliver thee to the judge, and the judge deliver thee to the officer, and thou be cast into prison.
26Verily I say unto thee, Thou shalt by no means come out thence, till thou hast paid the uttermost farthing.
