If we have difficulty loving someone, chances are that’s because we are starting from the wrong source: ourselves.
The perfect starting point is to draw from the love of God to us, then with hearts touched and afire, the supernatural outflow would be compassion to others.
Jesus also gave this principle on forgiveness. In the parable of the ungrateful servant, a king forgave a wretched servant of 10,000 talents, therefore the expectation is for that servant to forgive a fellow servant of a comparative few amount.
The best vantage point to love the unlovable is to realize that, objectively speaking, we would be unlovable to God because of our inner filth and mess, but He lavishes His favor on us to the point of sending His Son to the Cross for us.
Once we have tasted this kind of unmerited favor, it would be unthinkable for us to withhold the same affection to those we think don’t deserve it.
Have a great workweek ahead!
