The best answer I ever heard to life was this:
And behold, a certain lawyer stood up and tested Him, saying, “Teacher, what shall I do to inherit eternal life?” 26 He said to him, “What is written in the law? What is your reading of it?” 27 So he answered and said, “ ‘You shall love the Lord your God with all your heart, with all your soul, with all your strength, and with all your mind,’ and ‘your neighbor as yourself.’” 28 And He said to him, “You have answered rightly; do this and you will live.”
To explain love your neighbour Jesus then used the Good Samaritan story about helping others who need your help. There was racism between Samaritans and Jews but Jesus didn't accept discrimination, the bible says there is neither male nor female, neither Greek nor Jew.
