Truth is not truth without love. Tolerance is incomplete without love. Justice is dangerous without love. So love is a demand. I learned a sentence years ago when I was in theological seminary.
Love is a decision .
When I married my wife, I'm not sure how much I loved her when I married, but it was a decision. Then follows the next question the question of love is in the future. Love is a decision. That is what mature adulthood is all about. When you make a decision, you are moving out in the dimension where you can grow and become more than you are today.
