"Christ instituted a New Covenant with believers." is very important as well as Jesus' answer about healing on the Sabbath (Mark 3:1-6). I think there is a small verse about resting at night and meditating on God's word. Just the same a good friend of mine saidhow every evening he would think about his day and review his day - where he had fallen short of his goals and what went right. He was the one who turned me to seek God for help. (And God actually did rescue me, and then I was on my way to meet Jesus.)
