In this two volume work, Witsius, presents the reader with a fully biblical and experiential doctrine of the divine covenants; opening up their nature, stipulations, curses, and blessings.

Some smudges, annotations or unclear text may still exist, due to permanent damage to the original work. We believe the literary significance of the text justifies offering this reproduction, allowing a new generation to appreciate it.

This volume contains more than the title reveals. Prefaced to a 230-page exposition of the Lord¿s Prayer, Witsius devotes six chapters to the subject of prayer in general, which he calls the pulse of the renewed soul.
