The Sabbath is an institution in Scripture rooted in creation and in covenant. It finds its fulfillment in Christ; we find our Sabbath rest in him. But that doesn’t nullify our need to rest well physically from our labors. In fact I think that’s a part of learning to rest in God. As I think Martin Luther once said, he had learned to sleep well in the confidence that God is running the world, not himself.
For me this is important given the pressures and responsibilities I face, not to mention the ongoing concerns. True of us all. We need to learn to relax in all of life, dependent on God. Certainly easier said than done.
Do we believe that God is at work in our lives all the time for our good and the good of others? If it all depends on us, we will fall short for sure, or never be able to reach the goal. But if while we seek to be faithful, God is in the process toward completing his perfect work, then we can rest assured in him, that he will take care of it all.
God is present to help us in all our weakness. What we need to do is simply trust him, continue in faith so that we’re faithful. And not think for a second that the outcome depends on us. We do need to be present in faith to share in the blessing, but it’s God’s work. In and through Jesus.
