Contemporary English Version (CEV)
We can certainly understand God's sense of frustration. God was calling the people to live under his blessing of peace and abundance, but instead the people kept grasping for other solutions to their problems, other promises by lesser gods, things that could not deliver but perhaps seemed less intimidating, less distant, less challenging. God showed the people his abundance time and time again, but the people could not seem to follow.
We wonder at their foolishness, but at times, we live as fools as well. We settle for material things, thinking they will make us happy. We turn from the challenges of discipleship to look for easier paths to the promises only God can deliver. We seek to create our own rest rather than enjoy God's rest.
Only God can give what our hearts truly need. Only his holiness is capable of defeating the demons that torment us. When we understand this and stop settling for lesser solutions, we will take our steps toward the rest we can find in God alone.
