Calling out to God in times of distress often stems from a basic human need for safety. However, this plea for help goes beyond a simple desire for physical rescue or personal comfort. It is driven by a higher spiritual purpose, as the individual seeks to be saved from troubles strictly to be free to serve God. The repetition of the request for salvation, echoing an earlier prayer with different words, serves to emphasize and amplify the sheer intensity of the petition [רד"ק, מאירי].
The primary approach among commentators is that there is a direct cause-and-effect relationship at play. The individual asks God for salvation specifically so that, as a result, he can properly observe the Torah. This request is not rooted in a pursuit of private benefit or an easy life. Rather, it comes from a pure desire to act for the honor of God and to carry out His will [אלשיך].
On a practical level, the commitment to observe the Torah is made possible precisely through this divine intervention. When God saves a person from his enemies, that individual is finally freed from their constant harassment and the heavy burdens of conflict. With these distractions removed, he can dedicate himself entirely to keeping the Torah without any further interruptions [מצודת דוד, מלבי"ם].
