Christ Like Love

The Holy Spirit led me to a video today that literally touched my heart. How can we as Christians say that we are that way and treat others like they are not also a child of God. Why do we disdain someone else because of the lifestyle they live or their belief. The term Christian does not match our hearts. Our job as Christians is not to change that person, but to love that person. How do you love someone? How do you love someone that you do not agree with? I understand the definition of Love but how do you truly love someone?
