I recently heard Chuck Swindoll define biblical love. "Love is doing what's best for the other person, regardless." Regardless of the cost to you. Regardless of the other person. The other person might not reciprocate your love. Doesn't matter. The cost to you might not be appreciated by the other person. Love them anyway. Christian love is non-reciprocating.
That's how I want to love others, beginning with my family. Lord, help me to do so!
