The Greeks knew better than to only have one word for "love," they had four.
Eros: The whole sphere of sexual attraction and carnal desire.
Bible... Song of Solomon
Storgos: The natural affection one might feel for our children, parents, tribe, or country.
Philia: The love of friendship.
Agape: The highest form of love given. Selfless and unconditional. So strongly desires the good of the other, that it is willing to sacrifice itself. It is also the form of love shown in forgiveness.
John 3:16, For God so loved the world that he gave* his only Son, so that everyone who believes in him might not perish but might have eternal life.
John 13:34-35, I give you a new commandment: love one another; you must love one another just as I have loved you. It is by your love for one another, that everyone will recognize you as my disciples.
John 21:15-17, When they had finished breakfast, Jesus said to Simon Peter, “Simon, son of John, do you love me more than these?” He said to him, “Yes, Lord; you know that I love you.” He said to him, “Feed my lambs.” A second time he said to him, “Simon, son of John, do you love me?” He said to him, “Yes, Lord; you know that I love you.” He said to him, “Tend my sheep.” He said to him the third time, “Simon, son of John, do you love me?” Peter was grieved because he said to him the third time, “Do you love me?” And he said to him, “Lord, you know everything; you know that I love you.” Jesus said to him, “Feed my sheep.
Each time Peter says love the Greek word is the verb form of philia. However, the first two times Jesus asks him, the word is the verb form of agape. Only in the last does Jesus meet Peter where he is: at philia.
1 John 4:8, Whoever does not love does not know God, because God is love.
1 Corinthians 13,
If I speak in the tongues of men and of angels, but have not love, I am a noisy gong or a clanging cymbal. And if I have prophetic powers, and understand all mysteries and all knowledge, and if I have all faith, so as to remove mountains, but have not love, I am nothing. If I give away all I have, and if I deliver my body to be burned,[a] but have not love, I gain nothing.
Love is patient and kind; love is not jealous or boastful; it is not arrogant or rude. Love does not insist on its own way; it is not irritable or resentful; it does not rejoice at wrong, but rejoices in the right. Love bears all things, believes all things, hopes all things, endures all things. Love never ends...
So faith, hope, love abide, these three; but the greatest of these is love.
