A person who cries out, "Father! Father!" only expresses his yearning.
Although he is calling out, his call is not heard–it does not go to the other end of existence.
Thus, a person should call out through the Torah, which is a sort of amplifier that creates a bond between human reality and God Himself.
The Torah is the name of God.
When a person reads the Torah, he calls out to God by name.
If a person instead simply calls out, that is not truly an outcry.
It is perhaps the expression of someone who wishes to call out, which too has value–nevertheless, one must call out principally with the correct instrument, the Torah, so that one's voice will reach God, be heard by Him, and elicit His appropriate response.
