“the whole nation had completed the crossing on dry ground” Joshua 3:17
God leads His people out of slavery and into the promised land. Both when leaving bondage, and when entering the promised land, God parts the water for His people. When leaving Egypt God divides the Red Sea, and when entering the promised land, God parts the Jordan river. When it comes to saving us and getting us to where we need to be, God makes a way. You can read more about the crossing of the Jordan in Joshua chapter 3 and chapter 4.
