"You have heard that it was said, 'You shall love your neighbor and hate your enemy.' But I say to you, Love your enemies and pray for those who persecute you, so that you may be sons of your Father who is in heaven. [...] For if you love those who love you, what reward do you have? [...] what more are you doing than others?"
This is pretty stinkin' convicting. Half of the time, I don't even love those who are loving me. My heart is smaller than that of the Grinch; when the Hoo's do start loving him, he at least loves back.
Let's take it back to early sunday school days, "For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life," John 3:16. I remember my pastor (shout out to Pastor Teacher Harry Reeder) one time saying that the biggest word in this verse is the third one, "so." God SO incredibly much loved the incredibly sinful world that he sacrificed our King for those who hate Him most.... Me on the other hand? Like I said, I don't even love those who loved me first.
New year's "resolution" (more like prayer)-- be so filled up with God's perfect love so that it (and not my own selfishness) is what pours out of me onto everyone I encounter.
