By obeying it. Orthodox Jews believe that the Torah must be fully observed. Other Jewish groups (Conservative, Reform) adapt, curtail or change the Torah-laws in contemporary life, to a greater or lesser degree.
Religious Jews live by the Torah, by obeying its commands and beliefs.Link: Jewish beliefs
Some examples of the commands:
And many more.
The laws have various reasons. Some (such as the Passover) serve to reenact or remember events of our history.
Some (such as saying the Shema-prayer) serve to reiterate our belief in God.
Some of the laws (such as those of ritual purity and kosher food) serve to sanctify us.
Some (such as the laws of torts) serve to maintain an orderly and just society.
Some (such as the law against breaking a vow) serve to prevent bad character traits.
Some (such as the command to offer help) serve to engender good character traits.
And all of the commands serve to subjugate us to God's will (especially those commands for which no explanation is easily apparent).
Note that the Torah "as is" isn't exactly what Judaism observes. Rather, It's the Torah together with the details provided in the Talmud, which is the Oral Law that was handed down together with the laws of Moses. Otherwise, the verses of the Torah often lack enough detail to be fulfilled as is.
