"Because of your faith, you are saved." The idea of "faith" can be translated with a verb: "Because you believe, you are saved." (See: [[rc://en/ta/man/translate/figs-activepassive]])
This is a way of saying "good-bye" and giving a blessing at the same time. It can be translated as "As you go, do not worry anymore" or "May God give you peace as you go" (UDB).
