Author Description

John Jackson (1600-1648) was a Westminster Puritan divine with a hearty theological intellect, and tender pastoral understanding. What makes a worthy minister of the Gospel? We know that only God can make a minister, but what characteristics should a minister and his ministry demonstrate in the eyes of the church? Jackson's work focuses on his exposition of the stones in the High Priest's breastplate, as it is set down by Moses in Exodus 28:17-20, and the overlapping passage of Revelation 21:19-20 which concerns the stones seen in the walls of the New Jerusalem written by the Apostle John. Both the ministry of God's servants in the Old Testament and New Testament have certain qualities represented in these stones. Jackson keenly explains these passages to demonstrate that ministers labor after the rich endowments and virtuous habits of grace, which they receive by coworking with God, and they do this by frequent repeated acts of prayer and preaching, to introduce such grace into their own soul and the souls of others by the power of God.The stones (sardius, topaz, emerald, carbuncle, sapphire, diamond, ligure, achate, amethyst, beryll, onyx, and jasper) show in each of their distinct respects, how a minister is to be worthy of the office of a servant, a comfort to the people, a light or fire in preaching the word, a chaste and holy man, one with a mind set on heaven, and the ability to bring the people "up to God" in preaching and prayer, and much more. In Jackson's explanation of each stone, he demonstrates the office and disposition of every true minister of the Gospel, as well as the description of their work, in "the virtue" of the stones and the meaning behind "the color" of each stone.
