In A Body of Doctrinal Divinity, John Gill argues for the existence and characteristics of the triune God. These arguments are all given from a heavily Calvinist perspective but he uses a lot of scripture to back up his claims. He also argues that the character of God is shown through his work on Earth by the elect and most importantly through Christ. These characteristics then carry on in the final stages of life, when human beings pass away and move on to heaven or hell.
In his book A Body of Practical Divinity, John Gill presents his beliefs on the worship of God. The first section of his text features advice to Christians participating in internal worship. According to Gill, the worshippers should experience thankfulness, humility, and self-denial as they commune with God. Next, Gill discusses the nature of public worship in the church and the special worship duties that belong to pastors, deacons, and church-members. Finally, Gill reviews the duties shared by individuals who participate in private worship. He warns us that the Triune God must remain the sole object of human worship. Gill's practical wisdom is useful for all Christians who aim to ensure that the act of worship is always glorifying to God.
