I put together this brief list of ten reasons I keep Torah:
10. My prayer would not be heard and would be a sin (Proverbs 28:9, Jeremiah 7:8-16).
9. When Messiah returns those who follow him will be obeying Torah and keeping the festivals (Ezekiel 45:16, Zechariah 14:16, Jeremiah 33:14-18).
8. There are over 1,089 commands from the Torah in the "New Testament".
7. If you obey one part of the Torah (such as "love your neighbor as yourself" or "Love the Lord your G-d with all your heart, and with all your soul, and with all your mind") you are required to keep the entire Torah (Galatians 5:3).
