“All sorts of people are fond of repeating the Christian statement that ‘God is love’. But they seem not to notice that the words ‘God is love’ have no real meaning unless God contains at least two Persons. Love is something that one person has for another person. If God was a single person, then before the world was made, He was not love. Of course, what these people mean when they say that God is love is often some- thing quite different: they really mean ‘Love is God’. They really mean that our feelings of love, however and wherever they arise, and whatever results they produce, are to be treated with great respect. Perhaps they are: but that is something quite different from what Christians mean by the statement ‘God is love’. They believe that the living, dynamic activity of love has been going on in God forever and has created everything else.
And that, by the way, is perhaps the most important difference between Christianity and all other religions: that in Christianity God is not a static thing—not even a person—but a dynamic, pulsating activity, a life, almost a kind of drama. Almost, if you will not think me irreverent, a kind of dance” (C. S. Lewis).
I don’t pretend to understand the concept of the trinity, but I do know that God didn’t create people because He was lonely. It wasn’t out of need that he made you and me. The Triune God had enough love and joy between the Father, Son, and Holy Spirit and was in perfect communion with Himself.
If anything, He created us out of an abundance of love that overflowed into something new. It’s a very little bit like when two people get married and the overflow of their love results in a baby boy or girl.
Love is giving, not taking. Love is sacrificial not selfish. If you want to know the true definition of love, look at who God is and what God has done. That is love.
