During the summer months I go to multiple churches on Sundays to compare sermons. In recent weeks, at several local churches emphasis has been placed on loving our enemies. I think after decades of trying to figure out how to love my enemies, if I have any, it would be this: There is no way I can do that by myself, so I share the love Jesus gave for me when he shed his blood on the cross.
In other words, the love Jesus has for me that dwells in my heart is how I am capable, willing and able to love my enemies. It works for me!
Just give it a try. Jesus is not wanting us to snub each other or hate each other. If you know and love Jesus, let Jesus' love within you be shared.
