Taharrush Jamai - A fruit of the Serpent.

When the restraining forces of our fallen nature are removed, then comes lawlessness.

Its simple really, man is fallen...

Jeremiah 17:9
The heart [of fallen man] is deceitful above all things, and desperately wicked: who can know it?

Thus, each and every one of us having been spoon-fed the serpent’s doctrine is capable of anything, which is why Jesus said that we must be born again...

John 3:7
Marvel not that I said unto thee, Ye must be born again.

...and that not of fallen flesh, but of the pure Spirit of God...

John 1:13
Which were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God.

Because the corruption of humanity that took place when Adam served Satan rather than God....

Romans 6:16
ye not, that to whom ye yield yourselves servants to obey, his servants ye are to whom ye obey; whether of sin unto death, or of obedience unto righteousness?

...has been inherited by us all. Which is why God will never allow humanity in its fallen state to enter His eternal order.

1 Corinthians 15:50
Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; neither doth corruption inherit incorruption.

Meaning, that if anyone of us had been handed over to a wild-eyed bearded Jihadist as a new-born babe, and spoon fed their doctrine of hate we would, each and everyone of us do as they do, which is why Jesus said. . .

Matthew 16:6
Take heed, and beware of the leaven of the Pharisees and of the Sadducees.

Meaning. . .

Matthew 16:12
Then understood they how that he bade them not beware of the leaven of bread, but of the doctrine of the Pharisees and of the Sadducees.

It is the doctrines of the serpent which we who know our God must guard against. . .

Proverbs 4:23
Keep thy heart with all diligence; for out of it are the issues of life.

For what we accept in our heart will thereafter determine our behaviour. . .

Matthew 15:19-20
19 - For out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies:
20 - These are the things which defile a man: but to eat with unwashen hands defileth not a man.

Therefore it is by a man’s works, especially in lawless times that you will know what is in his heart.

Matthew 7:20
By their fruits you will know them.

James 3:14-16
14 - But if ye have bitter envying and strife in your hearts, glory not, and lie not against the truth.
15 - This wisdom descendeth not from above, but is earthly, sensual, devilish.
16 - For where envying and strife is, there is confusion and every evil work.
