God Himself Atoneth for the Sins of the World

Alma teaches that Christ’s Atonement occurred because God desired to extend mercy to us while still upholding justice.

“…Thus we see that all mankind were fallen, and they were in the grasp of justice; yea, the justice of God, which consigned them forever to be cut off from his presence. And now, the plan of mercy could not be brought about except an atonement should be made; therefore God himself atoneth for the sins of the world, to bring about the plan of mercy, to appease the demands of justice, that God might be a perfect, just God, and a merciful God also.” (Alma 42:14-15)

Questions: -How many realize they are in the grasp of justice without Christ’s intervention (which He made for those who repent)?
