You do know God is a God of justice, the world has seen some severe judgements upon many in the Old Testament
I do know that He is a God of justice, I also know what shape God's justice takes throughout Scripture. He is the God who champions orphans, widows, the poor, the needy, the hungry, and the foreigner. He is the God who freely, out of His kindness, justifies--makes righteous--the unrighteous.
When God judges it is not in opposition to His kindness and His compassion; He sends His rain upon the just and the unjust alike, He does not take pleasure in the death of the wicked, but says that He desires the wicked to repent and have life. St. Paul says that God's justice is revealed in the Gospel, what justice is that, a justice that condemns or the justice which saves, heals? It's the Gospel, so it's the latter.
Never mind what is going to happen in the future, it's going to be literally hell
The Scriptures which I read tell me that when Christ returns in glory to judge the dead will be raised and God will make all things new.
Or did you miss that bit?
Since I don't know what you have in mind, I can't comment.
God does not mend the worlds evil and brokenness, He forgives it, it's clear Christ is coming and it will be judged
"
Then I saw a new heaven and a new earth; for the first heaven and the first earth had passed away, and the sea was no more. And I saw the holy city, the new Jerusalem, coming down out of heaven from God, prepared as a bride adorned for her husband. And I heard a loud voice from the throne saying,
“See, the home of God is among mortals.
He will dwell with them;
they will be his peoples,
and God himself will be with them;
he will wipe every tear from their eyes.
Death will be no more;
mourning and crying and pain will be no more,
for the first things have passed away.”
And the one who was seated on the throne said, “See, I am making all things new.” Also he said, “Write this, for these words are trustworthy and true.”" - Revelation 21:1-5
"
I consider that the sufferings of this present time are not worth comparing with the glory about to be revealed to us. For the creation waits with eager longing for the revealing of the children of God; for the creation was subjected to futility, not of its own will but by the will of the one who subjected it, in hope that the creation itself will be set free from its bondage to decay and will obtain the freedom of the glory of the children of God. We know that the whole creation has been groaning in labor pains until now; and not only the creation, but we ourselves, who have the first fruits of the Spirit, groan inwardly while we wait for adoption, the redemption of our bodies. For in hope we were saved." - Romans 8:18-24
Make no mistake, the bible is about a righteous God who will condemn sinners who don't turn to Him for forgiveness
I find that fascinating in light of "The saying is sure and worthy of full acceptance, that Christ Jesus came into the world to save sinners—of whom I am the foremost." (1 Timothy 1:15)
For whom did Christ come? The righteous or the unrighteous? What does He tell you Himself?
"I have not come to call the righteous but sinners to repentance." (Luke 5:32)
You seem to conclude that God's default disposition toward the world is condemnation, and yet I read in John 3:16 that "God so loved the world that He gave His only-begotten Son". And also, "God demonstrates His love in that while we were still sinners, Christ died for us."
If you want to say that under the Law we stand condemned, I would absolutely agree--the Law making known to just the good, just, and right commands of God and thus, because we are unrighteous, we stand condemned simply because we see that the emperor--ourselves in this case--has no clothes. We read that God is unwilling that any should perish, God has not accepted the end of the world in sin and death, but has sent Christ, His only-begotten Son, to save the world, this He has done out of His great love for us.
So why would you assume that condemnation is God's default position toward us rather than the mercy and kindness revealed to us through Christ our Lord? Christ tells us He did not come to condemn but to save, we are condemned because we have, in truth, condemned ourselves through our sin--and it is precisely God in Christ saving us from our own self-made condemnation that is the revelation which we have in the Gospel.
