Can't you see how beautiful His creation?
How can you see the beauty without seeing the ugly too?
Did your all-loving god create HIV, cancer, smallpox, floods, drought, malaria, flesh-eating bacteria, leukemia, and poisonous snakes (to name a few)?
A reasonably powerful enemy did this.
God is correcting it with the New Heavens and the New Earth.
Jesus work on the cross did two things:
1. It kept this universe from being destroyed for a time, so that we would have time to live;
2. It opened the option for those who accept salvation to go to the New Place.
Since everything operates on principle, you need to believe in the salvation to get to the New Place.
