It's not any different than working, according to the principle in Isa 58:13:
Isa 58:13 "If you turn away your foot from the Sabbath, From doing your pleasure on My holy day, And call the Sabbath a delight, The holy day of the LORD honorable, And shall honor Him, not doing your own ways, Nor finding your own pleasure, Nor speaking your own words,
Mowing the lawn is not an essential task. With some planning, it can be done on another day; cleaning and grooming our bodies is essential to maintaining proper hygiene and setting a good example to the world; light is essential in safely performing tasks around the home in the evening; in this modern age, driving a car is our primary mode of transportation. Jesus and His disciples walked to services on the Sabbath. Today, we drive to them..
These are essential tasks which can endanger the health or cause discomfort to those involved. Even the strict Pharisees lead their oxen to water on the sabbath (Luk 13:15)
The whole point of properly keeping the Sabbath is based on principles of love toward man and God. It is a weekly reminder of the millennial rest and rejuvenation the entire world will enjoy after Christs Return (Heb. 3:11; I Pet. 3:8). Some keep it different than others. Discretion is encouraged as long as they abide by scriptural principles; keep it in faith (Rom 14:23) and on the
prescribed 24 hr period, God will honor it.
