It is the Patriarch's faith that catches our attention. As great as was Moses' faith , and the usefulness of the Law he gave, we always remember Abraham, Isaac, and Jacob because of their faith . And before them, we remember Noah and Job because of their faith . Any who do not believe following the Law is essential are beyond Judaism's understanding. Believing these ancient traditions are so important, some Jews can fail to spend much time discussing the need for, and value of personal faith.
Personal faith is different than intellectual belief or assent.
Knowing G-d is a relationship that goes far beyond creeds or repeated liturgies. It is a complete change of heart. Monologue prayer changes into dialogue prayer. Personal faith is knowing G-d personally as your Abba Father. This personal faith i s the goal of all religious acts .
