The answer is: Jordan

Matt 3:6

John the Baptist’s choice to baptize in the Jordan River is steeped in rich biblical history. The Jordan, a significant site in the land of Israel, is not just any river. It flows for over 250 kilometers, winding its way from the melting snows of Mount Hermon down to the Dead Sea, which everyone knows is too salty for fish! This river holds immense symbolism throughout the Bible, marking important moments like the Israelites’ crossing into the Promised Land under Joshua's leadership after their wanderings in the desert.

When John baptized people in the Jordan River, it wasn't just a casual dip! Baptism, derived from a Greek word meaning to immerse or dip, represented purification and a new beginning—not just for an individual but for an entire people returning to God. John’s calls for repentance resonated deeply in the hearts of many during this age of political unrest and religious expectation in Israel.

Moreover, John’s own connection to the Jordan foreshadows something even greater. Mystery surrounds his baptism of Jesus, which took place in the same waters, bridging the gap between old traditions and the dawning of a new way in spirituality. So in anticipating Jesus' life and message, recognizing the Jordan can remind us of that transformative step from old to new, echoing themes of renewal that are at the very heart of evolving spiritual understanding. Who knew such a humble river could carry so much meaning?
