God is Love. Where Love is, there God is. The Love of God is not abstract but is very tangibly revealed in the self-giving of our Lord Jesus Christ upon the Cross. This is the love God desires to reveal in us and through us — self-giving, other-centered, cross-shaped. St. Paul speaks quite splendidly and famously, in 1 Corinthians 13, on the nature of Love.
St. John the Theologian also brings us some important insights in the middle three chapters of First John. He tells us quite plainly that whoever loves has been born of God and knows God, and whoever does not love does not know God.
Dear friends, I am not writing you a new command but an old one, which you have had since the beginning. This old command is the message you have heard. Yet I am writing you a new command; its truth is seen in him and in you, because the darkness is passing and the true light is already shining. Anyone who claims to be in the light but hates a brother or sister is still in the darkness. Anyone who loves their brother and sister lives in the light, and there is nothing in them to make them stumble. But anyone who hates a brother or sister is in the darkness and walks around in the darkness. They do not know where they are going, because the darkness has blinded them. (1 John 2:7-11)
We know that we have passed from death to life, because we love each other. Anyone who does not love remains in death. (1 John 3:14)
Dear children, let us not love with words or speech but with actions and in truth. This is how we know that we belong to the truth and how we set our hearts at rest in his presence: If our hearts condemn us, we know that God is greater than our hearts, and he knows everything. (1 John 3:18-20)
Dear friends, let us love one another, for love comes from God. Everyone who loves has been born of God and knows God. Whoever does not love does not know God, because God is love. (1 John 4:7-8)
Whoever Loves Not Knows Nothing.
Whoever Loves Knows God,
For God is Love.
