We often hear people say, “I’m glad the weekend is here” and almost all are referring to both Saturday and Sunday.
However, to be accurate, Sunday is the first day of the week. The problem with the modern concept of “weekend” is that many people believe that this is their time to relax and play. There is nothing wrong with rest and relaxation, but we need to remember that God has given specific commands about the first day of the week. God wants us to meet on the first day of the week to worship Him.
