The term “geography of salvation” rarely appears in biblical theology. Occasionally, the term “sacred geography” is encountered. Yet it seems that the geography of salvation signifies much more than the sacred geography which means an arrangement of biblical events in space and their relationship with the sites. The geography of salvation, as proved in this article, implies a deliberate work of God who wanted to veil his Revelation not only in history but also in geography. It means that analysing the geographical environment of the sites related to biblical events and linking them with their function can lead to a discovery what God wanted to reveal by placing the events in the specific environment. The argumentation in the thesis was conducted on the basis of the River Jordan and its function in the synoptic Gospels against the background of the other books of the Bible. The conclusion of the article is the discovery that the River Jordan, and more precisely its geographical environment and function in the Bible, is a prefiguration of the baptismal initiation and the nature of the baptism itself.
