When you read about love in the Bible, you know that you are speaking about God. God is love. Of course, you do know about love. LOVE is not a need. Love is what St. Paul will tell us.
Love is patint, love is kind.
When you suffer for others you know what love is, and you know authomatically who is God and what God is. God is love. We exist to love and only to love. And love is a cross. A continuous giving, and everlasting giving.
