Loving the Unlovable

I am a simple man. Here is a complex issue.
I have no great theological training except growing up learning to love the Lord. God has blessed me with a gift of common sense and logic.
God says, “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 neighbor as thyself. On these two commandments hang all the Law and the Prophets.”
I sometimes wonder about the tests of human loving that present themselves to us. How do we love people who are not lovable?
The first thing that occurs to me is that we look at the person and find the good. What is it that is good or perhaps, was good in that person that has gone away? And then ask yourself, is this trait still there? Is it buried as a result of the human experience? Is it gone altogether and then what would God have us do?
But, how do I do this all the time and get around the fact that I am man?
God is in each of us including the unlovable. Not by our choosing, but by His.
One of our great challenges as we strive to live the life Jesus would have us live is this. Find God in that person. Is God, in that person, buried so deep that our seeking of Him is for our own spirit to grow and to learn?
Or is it different?
Is it that the Holy Spirit is working through us to help that person either find or rediscover God and His goodness in this world?
In either case, we are called to follow the great commission. And, in either case, we are forced to put our own human and personal emotions and prejudices aside and open ourselves to the goodness of the Holy Spirit so that God’s will be done.
Easy to do? No. Should we? Of course.
