The teachings of Jesus Christ that are beneficial to human kind

LOVE GOD AND NEIGHBOUR
When asked which commandment was the most important, Jesus
said, “Thou shalt love the Lord thy God with all thy heart, and with
all thy soul, and with all thy mind. This is the first and great
commandment. And the second is like unto it, Thou shalt love thy
neighbour thyself” (Matthew 22:37–39). The golden rule also applies in love for neighbours Therefore all things whatsoever ye would that men should
do to you: do ye even so to them: for this is the law and
the prophets (Matthew 7:12)

Loving God means keeping his commandments, and his
commandments are not burdensome.( 1john5:3)

loving your neighbours means love for all human being no prejudice, racist etc, forgiveness for all, kindness, peace with one another etc
You can't hurt a person you love, murder, sexual assault (fornication, adultery,rape,pedophile etc) cannot be done on person you love.
THE GOOD SAMARITIAN
a traveler who is
stripped of clothing, beaten, and left half dead alongside the
road. First a Jewish priest and then a Levite comes by, but both
avoid the man. Finally, a Samaritan happens upon the traveler.
Although Samaritans and Jews despised each other, the
Samaritan helps the injured man. Jesus is described as telling
the parable in response to the question from a lawyer, "And who
is my neighbor?" The conclusion is that the neighbor figure in
the parable is the one who shows mercy to the injured fellow
man

FREELY FORGIVE

Peter asked Him, “Lord, how oft
shall my brother sin against me, and I forgive him?” Jesus
responded, “I say not unto thee, Until seven times: but, Until
seventy times seven” (Matthew 18:21–22)
