Thomas Ridgeley's A Body of Divinity: Wherein the Doctrines of the Christian Religion are Explained and Defended, Being the Substance of Several Lectures on the Assembly's Larger Catechism is a book for which I have looked for well over a year. It is quite rare and does not appear in the used book market very often (I got it Tuesday!).
Here is a sample from the section on preparation for the Lord's Supper:
Another duty preparatory to the Lord's Supper, mentioned in this answer, is serious meditation. We are to perform this duty that we not engage in the ordinance without considering the greatness of the Majesty with whom we we have to do, together with our own vileness and unworthiness to approach his presence. We must also consider his power, wisdom, and goodness, to encourage us to hope for those supplies of grace from which we stand in need of; and we are to have an awful sense of his omnipresence and omniscience, as he is an heart-searching God, that we may be excited to an holy reverence, and guarded against the wandering of our thoughts and affections from him, or any unbecoming behaviour in his presence. More particularly, we are to consider beforehand, the end and design of Christ's instituting this ordinance- namely, that his dying love to sinners might be signified and showed forth, and an encouragement to our faith, and an inducement to thanksgiving and praise. -p534
