“The ark of the covenant led the people of God across the Jordan. The priests and the Levites halted, and the waters, as though out of reverence to the ministers of God, stopped flowing. They piled up in a single mass, thus allowing the people of God to cross in safety. As a Christian, you should not be amazed to hear of these wonders performed for men of the past. The divine Word promises much greater and more lofty things to you who have passed through Jordan’s stream by the sacrament of baptism: he promises you a passage even through the sky. Listen to what Paul says concerning the just: We shall be caught up in the clouds to meet Christ in heaven, and so we shall always be with the Lord. There is absolutely nothing for the just man to fear; the whole of creation serves him. Listen to another promise that God makes him through the prophet: If you pass through fire, the flame shall not burn you, for I am the Lord your God. The just man is everywhere welcome, and everything renders him due service.
...Mindful, then, of all the mighty works of God, remembering that he divided the sea for you and held back the waters of the river, you will turn to them and say: Why was it, sea, that you fled? Jordan, why did you turn back? Mountains, why did you skip like rams, and you hills, like young sheep? And the word of the Lord will reply: The earth is shaken at the face of the Lord, at the face of the God of Jacob, who turns stones into a pool and rock into springs of water.”
