Deuteronomy 6:5 And thou shalt love the Lord thy God with all thine heart, and with all thy soul, and with all thy might.
Leviticus 19:18 Thou shalt not avenge, nor bear any grudge against the children of thy people, but thou shalt love thy neighbour as thyself: I am the LORD.
Christ knew the Old Testament very well. He taught what was important.
I am also combing this with what I am learning from Froglogic. The popular 'feel good' positive thinking preaches "no fear exists." Froglogic http://www.teamfroglogic.com/navy-seal-blog/do-you-embrace-your-fear/ encourages anyone to embrace their fear and use it to power their determination to over come any challenge. I am fascinated by this concept. I'll probably have a few more post on embracing your fear to use it to improve life.
