Habits can be terribly bad or wonderfully good. The Psalmist's prayer was for a good habit. In fact, the best of all habits. The entirety of Psalm 119 is intended to convince us of the unbelievable value of listening to God through His Word and then following His directives.
There are people who are in perpetual turmoil. Life is always tumultuous to them. They are agitated and bothered, always in a hurry, constantly overwhelmed with the events of their week. When you are around them, it’s hard to take a breath. There is little rest and unceasing anxiety over the multiple details of their week.
