In other words, we should talk sparingly, softly, and sympathetically when in God's house. When we talk during the sermon, we may unintentionally be acting as a tool for the devil to distract those around us. For one thing, talking during the worship service demonstrates an attitude of unbelief that God is present and watching. It also shows that we do not think that God is speaking through His Word or His servant. When you talk while someone else is talking, it shows disinterest for what that person has to say.
Sleep shows a lack of perceived urgency.
We should plan our day so we are rested and alert during that sacred time. We attend church to commune with God and to hear His words that strengthen us against temptation. If we keep that in mind and pray earnestly for God to speak to us, He will do so every time-no matter how boring and dull the sermon may be. This is not a cringing silence for fear that the Lord might strike us if we make noise, but rather the hushed silence of joyous expectation. The Saviour of the world, the King of kings, my Lord and my God is present and has something to say to me today.
