In the time of trouble, if the people of God had unconfessed sins to appear before them while they were tortured with fear and anguish, they would be overwhelmed. Despair would cut off their faith, and they could not plead with God to deliver them. But they have no concealed wrongs to reveal. Their sins have gone beforehand to judgment and have been blotted out, and they cannot bring them to mind. LF 250.5
In His dealings with Jacob, the Lord shows that He will not tolerate evil. Satan will overcome all who excuse or conceal their sins and allow them to remain on the books of heaven unconfessed and unforgiven. The more honorable the position they hold, the more sure is their adversary's triumph. Those who delay their preparation cannot get it in the time of trouble, or at any later time. Their case is hopeless. LF 250.6
Jacob's history is also an assurance that God will not reject those who, lured into sin, have returned to Him with true repentance. God will send angels to comfort them in danger. The Lord's eye is on His people. The flames of the furnace seem about to consume them, but the Refiner will bring them through as gold tried in the fire. LF 250.7
