I read recently that the Chinese pictograph for "busy" is two different characters: heart and killing.
This is reason enough to take a look at your life and evaluate how you are living it.
Are you doing as Jesus instructed?
And He said to them, "Come aside by yourselves to a deserted place and rest a while." -Mark 6:31
Sabbath, or rest, is the womb where His words to us come alive and we are transformed.
And where our hearts come alive.
Is your heart dead or is it alive?
Are you "coming aside" to rest or are you pushing rest aside that you might get more accomplished?
There will be those in your life who choose not to rest and call it a "good work ethic." Do not let their dead, busy lives overshadow your own. Work hard and then come aside.
Come aside for rest and for a heart that lives.
