“The Sabbath rest is a rest He calls us to, but the surrendered rest He offers to us. The Sabbath rest we enter out of obedience; the surrendered rest we enter out of our need. The Sabbath rest arises from the good and perfect law of God; the surrendered rest arises from the good and perfect grace of God. The Sabbath rest is remembrance; the surrendered rest is meekness. Both provide soothing, God-ordained healing.”
