Bible literally says
Because God desires for everyone to spend eternity with him. He would not create a system where everyone won't have that opportunity.
This is good, and pleases God our Savior, 4 who wants all people to be saved and to come to a knowledge of the truth. - 1st Timothy 2:3-4
In the beginning, God gave a command. God knew that if they followed the command, they would never perish. But he also knew what as in store for them if they did not follow his command:
But of the tree of the knowledge of good and evil, thou shalt not eat of it: for in the day that thou eatest thereof thou shalt surely die. Genesis 2:17
God gives us free will. It is his will to let us all enter the Kingdom of heaven, but by our free will we deny ourselves that right.
Then someone has said (Not exact Quote)
Then why does God give us free will? Why doesn't he make us Obey?
Because then:
A: We would not be in his image.
B: There would be no reason for us to exist
C: We can surrender our free will, by having faith in him and doing his works.
God has written everyone's name in the book of life.
He foreordained everyone to go to heaven.
When you exercise your free will against him, your name becomes blotted out, and on the day of Judgement you are sent to hell forever.
This means that at the appointed time, God can say that he has know for all eternity just who would rebel and who would submit to his authority. But it made no difference to anyone because only he knew who was in that book and who was blotted out. No one knew other than this fair and just God.
Yet, knowing all this, this God of fairness and justice did not treat anyone unfairly. The Book of Life, written long before any life was ever created, will exonerate God from any and all charges of unfairness that Lucifer and unsaved mankind would have raised against him. If anyone should doubt this, then all they need to do is look at the record in the "other books", those books that have been recording every single thing that we have done during our life.
You saw me before I was born. Every day of my life was recorded in your books. Every moment was laid out before a single day had passed."
