In worship, quite a few aspects should concern the worshipper. In Gospel Worship, Burroughs is hammering home the idea that God must be regarded as holy to those who draw near to him in worship (worship of every kind). In the Lord's Supper this is especially true. From Sermon 11 - Consider this, that there is no duty in all the Bible that I know of, that is urged with more strength and severity than this ordinance. We find this in 1 Cor. 11 which shows the requirements of every one that comes to receive the bread and wine in the Lord’s Supper. They should, “examine themselves and so eat.” You have the most dreadful expressions against those that do not examine themselves in this that I know of mentioned against the neglect of any duty in all the Bible. There the Holy Spirit says, “that whosoever eats and drinks unworthily,” first, he is guilty of the body and blood of Christ. Secondly, he eats and drinks his own damnation. These two expressions have so much dreadfulness in them that you cannot even imagine it. We do not find an exhortation to a duty backed with two severe expressions like this (in case we should neglect our duty) as this great exhortation of eating and drinking worthily in the Lord's Supper. What if we do not sanctify God’s Name in this duty? We come to be guilty of the body and blood of Christ. Blood guiltiness is a terrible thing.
