Had this been a true story, I think you'd agree that it would be pretty silly. However, if you're keen on metaphors, think of the front yard as one's everyday life, the lawn mower as one's spirit, and the Owner's Manual as the Holy Bible. When looking at it that way, I'm sure you can see how the scenario I drew can unfortunately be 100% accurate. It is a terrible irony that some people get so consumed by trying to be right in their opinions about the Bible that they lose sight of the fact that they aren't acting in accord with its precepts. Colossians 3:12: Therefore, as God’s chosen people, holy and dearly loved, clothe yourselves with compassion, kindness, humility, gentleness and patience.
The moral of the story: DON'T BE HOLIER-THAN-THOU! God did not give us the Owner's Manual for the purpose of having us behave like Biblical know-it-alls -- belligerent, condescending, sanctimonious, and arrogant; He expects each of us to cut the grass.
"But the wisdom that comes from heaven
is first of all pure; then peace-loving, considerate, submissive,
full of mercy and good fruit, impartial and sincere."
