When the israeliets were bring led by Joshua to their Promised Land, an amazing incident occurred - the crossing of the River Jordan.

Believe it or not, this incident was also pointing to the future incident of the salvation of mankind by the blood of Christ. Let us see how.

Joshua 3:13 - "And as soon as the priests who carry the ark of the LORD -the Lord of all the earth—set foot in the Jordan, its waters flowing downstream will be cut off and stand up in a heap."
Today, our High Priest carried the New Covenant, the covenant of His blood and His Spirit.

Now think of the River Jordan to be the sin and judgement that awaits us, and we can't cross over into our Promised Land, heaven till that River separates us from it.

Joshua 3:15b-16a - "Yet as soon as the priests who carried the ark reached the Jordan and their feet touched the water's edge, the water from upstream stopped flowing."
The moment Jesus touched the judgement, or should I say, took it upon Himself, the River of Judgement stopped.
And not only did the River stop flowing, but "it piled up in a heap a great distance away, at a town called Adam" [Joshua 3:16]

And the amazing part is this -
"Herefore, just as sin entered the world through one man[Adam], and death through sin, and in this way death came to all men........
so also through the obedience of the one Man[our High Priest, Jesus Christ] many will be made righteous." [Rom5:12-19, Highlighting mine]
