We must not become disconcerted by the appearance of people. I remember being part of a worship team in one service in which a certain gentleman scowled at us for the duration of the service. I was convinced he had barely tolerated the entire thing. Afterward, however, he was very warm in expressing his sincere appreciation to us. That taught me the important lesson that we cannot always 'read' someone's receptivity by the expression on his or her countenance.
Some people can thoroughly enjoy a worship service but look miserable throughout.
We can place our affection on the Lord, radiate his joy, and stop fretting about people's response or lack thereof. Some churches encounter the problem of their worship style being offensive to visitors. Some people will always be 'offended' by the genuine move of the Spirit, and that is similar to the 'offense' our worship incurs, we can rejoice, for Jesus told us we would share his reproach. Genuine forms of praise and worship will not be repulsive to those whose hearts are pure before God. On the other had, we can boisterous and insensitive to culturally unacceptable forms of expression dance is an acceptable for of expression in our culture, but if it is executed by an obese person with no artistic from.
