So we see that because of their unbelief
they were not able to enter his rest.
Hebrews 3:19 NLT
REST and FAITH work hand in hand. What I believe about God determines whether I will enter His Rest. For example, my children believe that my husband and I will take care of them. They don't go to bed wondering if we will decide not to feed them tomorrow. They believe we are and will be good to them, therefore they rest.
Check your 'rest meter'. Are you resting or restless? Are you resting easy believing that God is and will be good to you? Are you trusting that He is able and willing to help you? He is working all of us toward a lifestyle of Rest as we trust in His Goodness.
