One cannot rely on H'shem and shrug off his own responsibility in choosing whether to do a Mitzvah, Averah or initiate an action. Relying on H'shem for this would be "foolish" since H'shem has left it in our hands to take action in either serving Him or rebelling against Him.

Nefesh Hachaim
We learn in Kabbalah, the three parts of the soul correlate to the three concepts that comprise man, as well as the makeup of every word in the Torah. The formula goes like this from lowest to highest:
Nefesh= Action=Letters of the Torah
Ruach= Speech= Vowel marks of the letters in the Torah
Neshama= Thought= Pronunciation marks (Trop) of the letters in the Torah
