To "love" people, you don't even have to like the individual, but love is a choice we make, not just to be "in love" with every person we meet, but to walk in love with the world. This is an attitude that permeates everything you do. It is an awareness that no one is greater than anyone else, and that others can feel the same joys and pains we feel. It is specially encourging as well as sobering to know that some of the people we may dislike intensely, are loved by God every bit as much as He loves us.
If you manage to live your life having joy, peace, patience, kindness, goodness, faithfulness, gentleness and self control towards others, then you will have managed to love, even those that you may find hard to like.
