IF the horrific sinner is sorrowful for sin, God will forgive.
God does HATE sin in His children, but not the sinning child.
Every person is a magnificent creation of God that has become infected with the malignancy of sin. He wants you to accept the vaccine delivered by the blood of Jesus.
If a person is 'good' but never takes the vaccine, that person is just as doomed as the 'bad' person who defies God to His face...
Those who come to his son Jesus find full forgiveness of all sins, past, present and future.
God does hate sin.. it is an offense to Him.. He is a just God and will dispense justice to all those that have sinned .. that is not vengeful it is justice giving to everyman what he deserves..
It seems we should clarify the context first. You seem quite sincere and have asked an intelligent question.
Unfortunately however, this question is often asked by others based on a preconceived premisea silly, dumb, Oprah Winfrey-generated notion of life. Remember that pride (self-centeredness) is the way of the fool.
Most importantly, God is not human and we can neither know Gods complete plans or his thoughts nor can we judge him as we judge humans.
God is vengeful, in a way that we cannot fully understand. And God is loving, but also to an extent that we cannot fully appreciate.
The answer is not to be found exclusively in any human forum. We must stand on Gods word.
So God is not vengefull , he does not hate or have grudges. He forgives even the most horrific sinners?
Is this a rhetorical question? So far, I can see that nearly everyone who has responded has a very unbalanced and erroneous comprehension of God and the doctrines of Redemption. "Vengeance" is throughout the Bible, from Genesis to Revelation, it is a property and defining characteristic of God. Here is an interesting "one stone - two birds" sort of passage from the prophet Nahum (1:2-3)
God is jealous, and the Lord avenges; The Lord avenges and is furious. The Lord will take vengeance on His adversaries, And He reserves wrath for His enemies; The Lord is slow to anger and great in power, And will not at all acquit the wicked.
In Psalms 5:5 we know that God hates "all workers of iniquity" and will "destroy those who speak falsehood". Which doesn't sound like the milk toast, hand wringing god that others are describing for you.
So we know that there are many who God hates, and we know that there are many who God loves, and we know that God made many men specifically as vessels of His wrath (Ro 9:22) and others specifically as vessels of His Mercy and Grace (vv 23-24), and that only those whose sins have been forgiven shall receive eternal life (Eph 1:7), while there are many who shall never receive forgiveness (Mark 3:29)
So how does one obtain this forgiveness? By repentance and faith in God's Son. How do we, all of whom have hated God turn from our hatred to kinship? Through the work of the Paraclete to change the heart of stone to flesh. (Ezek 36:26-27) Who will receive this work of Grace? Those who He has chosen from eternity past (Eph 1:4-6).
So who receives forgiveness of sins? Ultimately, just the Elect of God.
The broken and contrite spirit He will in no way cast out. But the haughty and proud He will not hear. He is the ‘Deliverer’ from your tresspasses and sins, but you have to ask for His Deliverance to receive it. It is in His purview to acknowledge the plea where/when He decides ... including in any Time of that broken and contrite spirit.
