Happy Labour Day!! Most people are possibly resting on a day like today or got an extra day if they worked Sunday.
but the seventh day is a Sabbath day of rest dedicated to the Lord your God. On that day no one in your household may do any work. This includes you, your sons and daughters, your male and female servants, your livestock, and any foreigners living among you. For in six days the Lord made the heavens, the earth, the sea, and everything in them; but on the seventh day he rested. That is why the Lord blessed the Sabbath day and set it apart as holy.
Most places in North America get Sunday as a day of rest, some people go to church or take that time to pray and read. There`s some that don`t go to church and may work on Sunday`s or stay home. We all need to make money to put food on the table, a roof over our head, bills be paid, our bodies being clothed. Besides it`ll be abit chilly and akward if we dressed like Adam and Eve once upon a time.
The bible says not to be lazy, but the bible also reminds us to just take some time to rest as well. Labour Day is often on a Monday as Sunday is usally a day of rest. Everybody needs a break from work if your constanly going hard, day in day out, but don`t let your spiritual life rest and wander away. Sometimes we just need to sit and listen, metitate on the Lord and let God teach, show us, mold us to be like Him. Keep it in balnce, when there`s no balance there can be too much build up or unorgainsed priorities sometimes.
Do the best you can do in life, always remeber to put God first and seek Him and he will bless you. 
Good thoughts. Unfortunately right now with harvest on, it's pretty hard to have a day of rest. I know I'll really enjoy it when I get to though! Regardless, your spiritual life cannot take a rest. God is always working in people's lives and we always need to be trusting in Him!
Im sure farming is differnt, most farmers tend to have a time limint for things or schedual/ I lived on a farm for a time of my life, I wasn't in the fields or working in the barns much but I still understand when i watched and herd my step dad with his farming work. God knows and understand where you have to be at.
Proverbs 10:4-5 says: lazy hands make for poverty, but diligent hands bring wealth. He who gathers crop in the summer is a prudent son, but he who sleeps during harvest is a disgraceful son.
Theres several verses that say about harvest, but I think this verse might be almost close. Praise God that He never takes a break.
