It is the most important commitment of the week. It is nothing less than meeting with God. Don't bring God left-overs. He cannot be satisfied with scraps. Get plenty of sleep on Saturday night and come to worship with an alert and refreshed mind.
Discipline begins in the mind and so does discipleship.
Train your mind to concentrate on spiritual things. Rushing in late makes it difficult for you to settle into meditation and it disturbs other worshipers. Coming to worship without your Bible is like going out to drive your car without your keys. Singing is not an option. It is a command.
