One cannot but wonder whether, in offering his prayers that morning, David had any presentiment of the trial that awaited him, anything to impel him to unwonted fervour in asking God that day to establish the works of his hands upon him. There is no reason to think that he had. His prayers that morning were in all likelihood his usual prayers. And if he was sincere in the expression of his own sense of weakness, and in his supplication that God would strengthen him for all the day's duties, it was enough. Oh! how little we know what may be before us, on some morning that dawns on us just as other days, but which is to form a great crisis in our life. How little the boy that is to tell his first lie that day thinks of the serpent that is lying in wait for him! How little the girl that is to fall in with her betrayer thinks of the snare preparing for her body and her soul! How little the party that are to be upset in the pleasure boat and consigned to a watery grave think how the day is to end! Should we not pray more really, more earnestly if we did realise these possibilities? True, indeed, the future is hid from us, and we do not usually experience the impulse to earnestness which it would impart. But is it not a good habit, as you kneel each morning, to think, "For aught I know, this may be the most important day of my life. The opportunity may be given me of doing a great service in the cause of truth and righteousness; or the temptation may assail me to deny my Lord and ruin my soul. O God, be not far from me this day; prepare me for all that Thou preparest for me!"
