• This mortal probation is a brief period-just a short span, linking the eternity of the past with the eternity of the future. Yet it was to be a period of tremendous importance. It is, in fact, the most vital period of our entire eternal existence. In this mortal state we come face to face with innumerable temptations and pressures. Sometimes we come in contact with advocates of wrongdoing, disobedience, and sin. Lucifer is going about tempting those who can be tempted to see if he can lead them astray.
