For me rest is more than a good sleep. Rest is peace. Rest is "shalom" - completeness, wholeness, peace, soundness, tranquility, fullness, harmony, the absence of agitation or discord. Rest is being okay with who I am.
Rest is turning off all that noise - television, laptop, phone, the task list I keep in my brain, the expectations I have for myself - all of those things that keep my mind spinning. Rest is not pulling out my iPhone to check my email in the doctor's waiting room but taking a page from those olden days when instead I would simply observe my surroundings. Rest is taking those few spare minutes to sit down and close my eyes instead of picking up my book or the newspaper. Rest is not making a To Do list, even though checking off those tasks is so very satisfying to me.
Rest is being quiet and listening to my heart, to what God is sharing with me today.
Jesus says, "Come to Me, all of you who are weary and burdened, and I will give you rest. All of you, take up My yoke and learn from Me, because I am gentle and humble in heart, and you will find rest for yourselves." Matthew 11:28-29
