If worshipers leave a [worship gathering] with no thought of becoming more godly in their lives, then the purpose of worship has not been achieved. If they walk away from [a time of worship] without a conviction that they need to conform their lives to Holy Scripture, even if it means changing their lifestyle, then worship has been perverted somehow… The clear teaching of Scripture is that genuine worship is life changing

– Allen Ross

If you believe that worship is life changing then pray for it, plan / prepare for it, and expect it.
