What does the Bible say about the essence of love?

In 1 John 4:10-11, we learn that the essence of love is not found in our love for God, but in His love for us, demonstrated through the sending of His Son to be the propitiation for our sins. This passage highlights that genuine love is defined by God's initiative rather than human effort. The love discussed in Scripture is rooted in truth, characterized by sacrifice, and demands a response of love towards others. Understanding this divine love shapes how Christians interact with one another, emphasizing that true love reflects God's nature.
