I have worked on Saturday/Sunday (as a newspaper deliveryman).
But, for most of my working career, I was spared from having to work much on the weekends. In this way, I have been blessed.
But, I note that there are many who work by necessity on the weekends, ... for instance doctors, nurses, firemen, policemen, etc. I once had to carry my wife to Emergency on Sunday afternoon. I was very grateful that there were doctors, nurses, and hospital staff working that day.
Jesus said that "The Sabbath was made for man, ... and not man for the Sabbath." I interpret this to mean that God has given the Sabbath to humanity as a time of rest and respite from labor and the sccompanying cares of this world. In other words, ... it is to be a benefit to us ... and not a burden or hindrance to doing that which is good.
The 4th commandment says "Remember the Sabbath, ... to keep it holy."
I believe that God desires that we not forget, ... or treat with disdain His Sabbath ... when He rested from His creative endeavors.
And I believe that God desires that we take time to REST and REFLECT, and to GATHER in His name. Though the weekend migh be a preferred time for this, ... it can also be accomplished on other days of the week.
It is the SPIRIT of the LAW that we attempt to meet, ... not necessarily the LETTER.
Paul taught God's desire that we pursue the SPIRIT of the LAW, as opposed to the LETTER, in the following passages ...
“Not that we are adequate in ourselves to consider anything as coming from ourselves, but our adequacy is from God, who also made us adequate as servants of a new covenant, not of the letter but of the Spirit; for the letter kills, but the Spirit gives life” (2 Corinthians 3:5-6).
“But he is a Jew who is one inwardly; and circumcision is that which is of the heart, by the Spirit, not by the letter; and his praise is not from men, but from God” (Romans 2:29).
... and Jesus illustrated this principle in the (2) examples I have previously offered.
