For extroverts, finding silence during a week is very important even though silence isn’t their natural leaning. For introverts, finding silence is easy since they prefer less stimulation on any given day. For both groups, silence speaks volumes. When you choose to practice silence you tell others something about you and your priorities.
When we become Christians, we don't merely choose an eternity in heaven over hell. Rather, we are "born again"; like a newborn child, each of us enters into a new life that we fully inhabit, day-in and day-out. God desires that we pursue a relationship with him every day, in all aspects of life. When we try to live daily life for the sake of his glory, he deems it sacred.
