Since billions of people suffer because of Adam's sin, wouldn't there have been a better and faster way to solve the problem?
After Adam and Eve's sin, why did God permit their descendants to become imperfect? Since manking has to become perfect once more during the millenium, for the only purpose of being tested once more by Satan in order to obtain eternal life.
Couldn't the descendants of Adam have remained perfect and they could have chosen, either to obey God or Satan?
That could have saved thousands of years, and billions of people from suffering.
