It is egregiously unjust that you could not do it because you did not know.
If you had known, you would have done it, but you could not do it because you did not know.
Therefore, not knowing is truly unjust.
Get out of ignorance by learning every day.
Those, who live in Hell and in the domain of death, do not know.
They went to Hell because they did not know. Especially, they did not know God.
If you know, you will live. If you do not know, you will die.
