People have free will. They can choose evil. There is a distinction between good and evil. Good is that which is in keeping with our human nature. Evil is that which is in opposition to it.
Modern liberalism says both are the same. Modern liberalism gives people permission to do evil, and then blames society.
Modern liberalism is the problem.
There was a time, I remember, that people had something called “shame” if they did wrong. Other people reminded them of their need to be ashamed. Today, there is no shame.
You said, "Good is that which is in keeping with our human nature. Evil is that which is in opposition to it." But is that really biblical? Let's break it down.
First, you said "Good is that which is in keeping with our human nature." The Bible directly contradicts that in many places.
1. Genesis 6:5 says, "And GOD saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually."
2. Genesis 8:21 says, "And the LORD smelled a sweet savour; and the LORD said in his heart, I will not again curse the ground any more for man's sake; for the imagination of man's heart is evil from his youth; neither will I again smite any more every thing living, as I have done."
3. Psalms 34:14 says, "Depart from evil, and do good; seek peace, and pursue it." Psalms 37:27 says, "Depart from evil, and do good; and dwell for evermore." To ask someone to depart from evil would have to imply that he was there in the first place.
4. Ecclesiastes 8:11 says, "Because sentence against an evil work is not executed speedily, therefore the heart of the sons of men is fully set in them to do evil."
5. Again in Ecclesiastes 9:3 it says, "This is an evil among all things that are done under the sun, that there is one event unto all: yea, also the heart of the sons of men is full of evil, and madness is in their heart while they live, and after that they go to the dead."
Lastly on this first point, the words of Our Savior Jesus when He rebuked the religious hypocrites of his day, from Matthew 12:34 where He says, "O generation of vipers, how can ye, being evil, speak good things? for out of the abundance of the heart the mouth speaketh."
Going back to my original post, the only way this condition can be changed, truly changed, is through repentance and faith in Jesus Christ.
John 3:5-7 says, “Jesus answered, Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God. That which is born of the flesh is flesh; and that which is born of the Spirit is spirit. Marvel not that I said unto thee, Ye must be born again.”
On to the second point you raised, "Evil is that which is in opposition to it (our human nature)." Here we have an equation: Evil = opposition to human nature. Is that biblical?
Again, let's go to God's Word.
John 3:16-21 says this, "For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. For God sent not his Son into the world to condemn the world; but that the world through him might be saved. He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God. And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil. For every one that doeth evil hateth the light, neither cometh to the light, lest his deeds should be reproved. But he that doeth truth cometh to the light, that his deeds may be made manifest, that they are wrought in God.
Can you see what I'm getting at in this passage. Evil is whatever is contrary to "the light." Basically, our equation now looks like this: Evil ≠ Light. So basically, evil is whatever is opposed to the light, Jesus Christ.
Lastly, "the problem." The problem has many manifestations, but the root cause is always the same, and it's same thing that befell Lucifer; "pride." From "pride" comes "sin," and from "sin" we have the problems we have today.
Whew, man, I tell you what, I felt a "preach" come upon me last night and it still hasn't abated. Don't know how much more of this I can take!
