The return of her sons without harm allows Sariah to believe in her husband as a prophet. In addition to now "knowing" that the Lord had protected her sons, and delivered them from Laban, she also indicates that she now knows "of a surety that the Lord hath commanded my husband to flee into the wilderness." There is nothing in the return of her sons which provides any level of "proof" that the flight into the wilderness was inspired, yet she believes. This bolsters even further Sariah's willingness to believe Lehi - right up to the point where her son's lives were thought to have been forfeit.
