Proverbs 6:16-19 NKJV
These six things the LORD hates, Yes, seven are an abomination to Him:  A proud look, A lying tongue, Hands that shed innocent blood,  A heart that devises wicked plans, Feet that are swift in running to evil,  A false witness who speaks lies, And one who sows discord among brethren.
Jesus Informs Us Of The Work Of The Holy Spirit
John 16:5-8 NKJV
“But now I go away to Him who sent Me, and none of you asks Me, ‘Where are You going?’  But because I have said these things to you, sorrow has filled your heart.  Nevertheless I tell you the truth. It is to your advantage that I go away; for if I do not go away, the Helper will not come to you; but if I depart, I will send Him to you.  And when He has come, He will convict the world of sin, and of righteousness, and of judgment:
Human beings are Born Again by the Spirit of God.
John 4:23-24 NKJV
But the hour is coming, and now is, when the true worshipers will worship the Father in spirit and truth; for the Father is seeking such to worship Him.  God is Spirit, and those who worship Him must worship in spirit and truth.”
Therefore…When He has come, He will convict the world of sin, and of righteousness, and of judgment:
Specific sins must be preached against.
Gods Righteousness, Majesty, and Holiness must be proclaimed.
People must be warned and informed about the consequences of Judgement from God, when they reject His Son Jesus Christ as Lord and Saviour. Hell awaits those who are lost and dead in their trespasses and sin. Jesus says,
John 3:3-8 NKJV
Jesus answered and said to him, “Most assuredly, I say to you, unless one is born again, he cannot see the kingdom of God.”  Nicodemus said to Him, “How can a man be born when he is old? Can he enter a second time into his mother’s womb and be born?”  Jesus answered, “Most assuredly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God.  That which is born of the flesh is flesh, and that which is born of the Spirit is spirit.  Do not marvel that I said to you, ‘You must be born again.’  The wind blows where it wishes, and you hear the sound of it, but cannot tell where it comes from and where it goes. So is everyone who is born of the Spirit.”
Revelation 20:12-15 KJV
And I saw the dead, small and great, stand before God; and the books were opened: and another book was opened, which is the book of life: and the dead were judged out of those things which were written in the books, according to their works.  And the sea gave up the dead which were in it; and death and hell delivered up the dead which were in them: and they were judged every man according to their works.  And death and hell were cast into the lake of fire. This is the second death.  And whosoever was not found written in the book of life was cast into the lake of fire.
Revelation 21:27 NKJV
But there shall by no means enter it ( Heaven ) anything that defiles, or causes an abomination or a lie, but only those who are written in the Lamb’s Book of Life.
If you have not been Born Again, you will be cast into the lake of fire, which is eternity in hell. That is The Judgement that must be preached, proclaimed, and people must be warned about.
YEARS I SPENT IN VANITY AND PRIDE,
CARING NOT MY LORD WAS CRUCIFIED,
KNOWING NOT IT WAS FOR ME HE DIED
MERCY THERE WAS GREAT
AND GRACE WAS FREE,
PARDON THERE WAS MULTIPLIED TO ME,
THERE MY BURDENED SOUL
BY GOD’S WORD AT LAST
MY SIN I LEARNED,
THEN I TREMBLED
AT THE LAW I’D SPURNED,
TILL MY GUILTY SOUL,
NOW I’VE GIVEN TO JESUS EVERYTHING,
NOW I GLADLY OWN HIM AS MY KING,
NOW MY RAPTURED SOUL CAN ONLY SING
OH! THE LOVE THAT
DREW SALVATION’S PLAN,
OH! THE GRACE THAT
BROUGHT IT DOWN TO MAN,
OH! THE MIGHTY GULF
THAT GOD DID SPAN
