Apparently Mary and Martha and the dying Lazarus were left alone. But they were not alone. Christ beheld the whole scene, and after the death of Lazarus the bereaved sisters were upheld by His grace. Jesus witnessed the sorrow of their rent hearts, as their brother wrestled with his strong foe, death. He felt every pang of anguish, as He said to His disciples, "Lazarus is dead." But Christ had not only the loved ones at Bethany to think of; He had the training of His disciples to consider. They were to be His representatives to the world, that the Father's blessing might embrace all. For their sake He permitted Lazarus to die. Had He restored him from illness to health, the miracle that is the most positive evidence of His divine character, would not have been performed.
Had Christ been in the sickroom, Lazarus would not have died; for Satan would have had no power over him. Death could not have aimed his dart at Lazarus in the presence of the Life-giver. Therefore Christ remained away. He suffered the enemy to exercise his power, that He might drive him back, a conquered foe. He permitted Lazarus to pass under the dominion of death; and the suffering sisters saw their brother laid in the grave. Christ knew that as they looked on the dead face of their brother their faith in their Redeemer would be severely tried. But He knew that because of the struggle through which they were now passing their faith would shine forth with far greater power. He suffered every pang of sorrow that they endured. He loved them no less because He tarried; but He knew that for them, for Lazarus, for Himself, and for His disciples, a victory was to be gained.
"For your sakes," "to the intent ye may believe." To all who are reaching out to feel the guiding hand of God, the moment of greatest discouragement is the time when divine help is nearest. They will look back with thankfulness upon the darkest part of their way. "The Lord knoweth how to deliver the godly," 2 Peter 2:9. From every temptation and every trial He will bring them forth with firmer faith and a richer experience. Desire of Ages - pape 528
