I do not know John Harrigan or the context of this quote, but it is a challenging thought. It is so easy to love people who are easy to love! Cute kids, loving spouses and lifetime friends are easy to love. They make us happy; we enjoy being around them and loving them. More challenging to love might be the demanding and unfriendly boss or the self-centered co-worker. And then there are the homeless, the sick, the chemically dependent, and the criminals. What makes them deserve love? Possibly those who need it the most are those who we truly do love, but because of the current circumstances we might not feel them to be deserving. Consider the misbehaving teenager, the angry friend, and the betraying spouse. It may be the hardest to love those close to us when they have wronged us or misbehaved. Biblically we are called to love, not just those that are easy to love.
