If you cannot worship the Lord in the midst of your responsibilitie s on Monday, it is not very likely that you were worshiping on Sunday!
If you do not worship God seven days a week, you do not worship Him on one day a week. There is no such thing known in heaven as Sunday worship unless it is accompanied by Monday worship and Tuesday worship and so on.
If you're not worshiping God on Monday the way you [did] the day before, perhaps you're not worshiping Him at all.
