God abolished sin. This is only for the Chosen, of course. He did abolish sin by providing full atonement for it and predestinating His transformation in his sons and daughters. He no longer remembers sin in his Chosen ones and he has predestined all who are his to be conformed into the image of his Son:
Hebrews 10:14-18
For by one offering he has perfected forever those who are sanctified. The Holy Spirit also testifies to us, for after he has said, "This is the covenant that I will make with them: 'After those days,' says the Lord, 'I will put my laws on their heart, I will also write them on their mind;'" then, "I will remember their sins and their iniquities no more." Now where remission of these is, there is no more offering for sin.
That's not quite the way salvation works. Certainly you don't mean anyone outside of God's covenant. No one outside of God's Covenant is saved.
Finally, you suggested that "God has left the world this way." That's not the preterist view. The preterist view understands that God has spread his covenant and people globally in just 20 centuries and they will continue to subdue kingdoms and establish God's laws and righteousness over all regions of the planet and perhaps even beyond the planet someday. Remember, back in Christ's day only one tiny land on the planet had any knowledge or access to Jehovah. That land was approximately about 200x100 miles in size. The rest of the entire planet was in darkness.
20 centuries later, the knowledge of Jehovah and his Covenant has spread to nearly all known regions of the planet in the first level of God's ongoing reconciliation carried out through Christ's own body. Christ's Nation is predestined for eternal success in its purpose and mission and the People of God. Jesus said that the meek ones of Israel would inherit the earth, and Paul declared that Genesis 12:1-3 was coming to pass via the inclusion of the gentile populations (see Gal 3:8-9).
Christ, Abraham and their sons and daughters in the Nation of Christ have inherited all things (Romans 4:14-18). Christ and the Church have been given all dominion (1 Peter 4:11; Eph 1:21; Jude 1:25; Rev 1:6; Daniel 7:14,27).
So not only did Yahweh choose to not leave the entire planet under total darkness, He has given all things to Christ and the Church who are exercising their rights and dominion over the planet and are the only eternal Nation upon earth.
