“Light drives out darkness. Love drives out hate.”
First, one needs to personally know the Source of light and of love.
Then, one needs to understand what love is, and what love is not.
Love is willing the good of the other. Love is not a feeling. Love is an act of the will; a choice; a decision; often gut wrenching and difficult.
We can not love our neighbors without also loving our enemies, because they are often the same persons. Find a crucifix and really study it for a while. That’s the kind of love that drives out hate.
Can we “really” love each other? Or are we simply calling for an ineffectual, feel-good, sentimentality? Can we love our enemies? Not without the Source of light and of love. Not by our own power
