What do the twelve stones represent in Joshua's crossing?

In Joshua 4, the twelve stones taken from the Jordan River symbolize the completeness of God's salvation plan and His faithfulness to His people. Each stone represents one of the twelve tribes of Israel, commemorating their crossing into the Promised Land on dry ground—an act entirely dependent on God's miraculous power. This event illustrates that every member of God's chosen people was delivered safely, just as every elect believer will ultimately receive grace and salvation through Christ. The stones served as a perpetual reminder to future generations of God's mighty works and His covenant faithfulness—signifying that all those whom the Father gives to the Son will come to Him; none will be lost. Thus, these stones stand as a testimony of assurance in God’s promise of salvation.
