The Keeping is to be Continuous.
Every morning God Will Meet you as you wake.
It is not a question of “if I should forget to wake in the morning with the thought of Him, what will come of it?”
If you Trust your waking to God, God will Meet you in the morning with His Divine Sunshine and Love, and He Will Give you the Consciousness that you Have Him to Take Charge of you Continuously with His Almighty Power.
And God Will Meet you the next day and every day.
