When Jesus ceases to plead for man, the cases of all are forever decided. This is the time of reckoning with His servants. To those who have neglected the preparation of purity and holiness, which fits them to be waiting ones to welcome their Lord, the sun sets in gloom and darkness, and rises not again. Probation closes; Christ's intercessions cease in heaven. This time finally comes suddenly upon all, and those who have neglected to purify their souls by obeying the truth are found sleeping. They became weary of waiting and watching; they became indifferent in regard to the coming of their Master. They longed not for His appearing, and thought there was no need of such continued, persevering watching. They had been disappointed in their expectations and might be again. They concluded that there was time enough yet to arouse. They would be sure not to lose the opportunity of securing an earthly treasure. It would be safe to get all of this world they could. And in securing this object…
"Watch therefore, for ye know neither the day nor the hour wherein the Son of man cometh."
EGW's passage directly alludes to the concept of watching and being prepared for the coming of the Lord, which is central to Matthew 25:13. She elaborates on the consequences of neglecting this preparation.
"If such had only known that the work of Christ in the heavenly sanctuary would close so soon, how differently would they have conducted themselves, how earnestly would they have watched! The Master, anticipating all this, gives them timely warning in the command to watch. He distinctly states the suddenness of His coming. He does not measure the time, lest we shall neglect a momentary preparation, and in our indolence look ahead to the time when we think He will come, and defer the preparation. “Watch ye therefore: for ye know not.” Yet this foretold uncertainty, and suddenness at last, fails to rouse us from stupidity to earnest wakefulness, and to quicken our watchfulness for our expected Master. Those not found waiting and watching are finally surprised in their unfaithfulness. The Master comes, and instead of their being ready to open unto Him immediately, they are locked in worldly slumber, and are lost at last. 2T 191.2"
"Watch therefore: for ye know not what hour your Lord doth come."
EGW directly quotes Matthew 24:42 and uses it as a basis for her discussion on the importance of watchfulness and the suddenness of Christ's coming.
