All around you there are people sitting in the pews during the worship assembly. Some are Christians, some are not. Some are strong Christians, some are not-so-strong Christians. Some are young and impressionable, some are old and set-in-their-ways. How is your behavior in worship affecting others? What are you doing during the sermon? Is what you’re doing (or not 
doing) a possible distraction or stumbling block for others? What are you doing during the Lord’s Supper? Is your talking, note-passing, goofing off, texting, playing games on your phone, etc. a distraction or stumbling block for others?
There are young children, teenagers and babes in Christ sitting within eyeshot of you in worship. Are you paying attention? Are you engaged in the worship? If you’re not, how can they be? You may not realize it, but you heavily influence the worship of others.
Let us make effort to help each other to honor and praise our God together!
