Moses took care of sheep for 40 years. Noah spent 120 years building the Ark. Job endured great suffering and hardships. All of these trying experiences helped them to develop great faith. One of the things that helped them to endure and to hold on during their trying times was the quiet meditation time they had with Me. If they hadn't taken time to meditate, they wouldn't have had the faith to endure.
So when you're going through a difficult time, spend time meditating on Me. Allow Me to work in your life and to nurture the faith you need in order to endure.
