Vincent explains what it means to prove ourselves, what it is to be proved, what we are to prove, the manner of proving, the rule of proving, special seasons of proving, and arguments for self-examination. He also shows differences between Christians and unbelievers in several cases of conscience, with a practical section of sin-mortifying application. He then concludes the book with how self-examination works prior to the Lord's Supper, and gives a number of personal meditations on how Christians should think before they come to the Lord's Supper.
