What does it mean that God is love in 1 John?

The statement 'God is love' encapsulates a profound truth about God's essence. In 1 John 4, this declaration signifies that all of God's actions and attributes are motivated by love. His love was supremely demonstrated in the sending of His Son, Jesus Christ, who became the propitiation for our sins. This profound act illustrates that God's love is active, sacrificial, and designed for the redemption of His people. Therefore, understanding God as love compels us to reflect this love in our interactions with others, embodying the truth of our relationship with Him.
