Let us therefore be zealous and exert ourselves and strive diligently to enter that rest (of God, to know and experience it for ourselves), that no one may fall or perish by the same kind of unbelief and disobedience (into which those in the wilderness fell).
We can be at rest daily, even when thoughts or circumstances tell us we need to “fix it”, or spend time worrying. When we aren’t at rest, we are in unbelief, not trusting that God will take care of it. The Israelites were in the wilderness because of unbelief and disobedience and didn’t get to live in their Promise Land. He wants us to rest in Him so we can receive the promises He has for us.
