“Everything is in the hands of G-d, except for the fear of G-d.” – Berachos 33b
“And now, Israel, what doth the L-RD thy G-d require of thee, but to fear the L-RD thy G-d, to walk in all His ways, and to love Him, and to serve the L-RD thy G-d with all thy heart and with all thy soul; to keep for thy good the commandments of the L-RD, and His statutes, which I command thee this day?” – Deuteronomy 10:12, JPS 1917 Tanach
Yiras H’Shem (fear of G-d) is a major component of one’s relationship to G-d; fear, in the sense of awe, reverence, and respect. The Torah records, “What doth the L-RD thy G-d require of thee, but to fear the L-RD thy G-d?” The quality of yiras H’Shem is what will determine the level of kedushah (holiness) in a person’s life. For our response to constant acknowledgment of G-d, will compel us to watch our own thoughts, speech, and behavior at all times, thereby elevating our level of kedushah.
Our response to H’Shem’s directive, through His commandments, requires giving Him the due respect that He deserves as our King. As a consequence of our reverence towards Him, we bring kedushah (holiness) into our lives through our obedience. We become sanctified through His commandments; every aspect of our lives may become sanctified (made holy). “Happy is everyone that feareth the L-RD, that walketh in His ways” (Psalm 128:1, JPS 1917 Tanach).
