In Hebrew, אהבה (ahava) is the most commonly used term for interpersonal love and the love between God and his creations. Chesed, often translated as loving-kindness, is used to describe many forms of love between human beings.
The command to love other people is given in the Torah, which says, “Love your neighbor as yourself” (Leviticus 19:18). The Torah command to love God “with all your heart, with all your soul and with all your strength” (Deuteronomy 6: 5) is taken from the Mishnah (a central text of the Hebrew oral law) to refer to good works , good will. sacrifice your life instead of committing certain serious transgressions, be willing to sacrifice all goods and be grateful to the Lord despite adversity (Berachot 9: 5). Rabbinic literature differs in how this love can be developed, for example by contemplating divine actions or witnessing the wonders of nature.
As for the love between spouses, it is considered an essential ingredient for life: “Look at life with the wife you love” (Ecclesiastes 9: 9). Rabbi David Wolpe writes that “… love is not just about the lover’s feelings … It is when a person believes in another person and shows it”. He also affirms that “… love … is a feeling that is expressed in action. What we really feel is reflected in what we do”.  The biblical book Song of Songs is considered a metaphor for love with romantic phrases. between God and his people, but on a simple reading, it reads like a love song. Twentieth-century rabbi Eliyahu Eliezer Dessler is often quoted as defining love from the Jewish point of view as “giving without expecting to receive” (from his Michtav me-Eliyahu, vol. 1).
The Christian understanding is that love comes from God. The love of man and woman (eros in Greek) and selfless love of others (agape) are often contrasted respectively as “descending” and “ascending” love, but in the end they are the same thing. .
There are several Greek words for “love” that are regularly mentioned in Christian circles.
Agape: In the New Testament, agapē is charitable, selfless, selfless and unconditional. It is the love of the parents, seen as a creation of goodness in the world; it is the way in which God is seen to love humanity, and is seen as the kind of love that Christians aspire to have for one another .
Phileo – Also used in the New Testament, phileo is a human response to something that is considered delicious. Also known as “brotherly love”.
Two other words for love in the Greek language, eros (sexual love) and storge (love from son to father), were never used in the New Testament. 
Christians believe that loving God with all your heart, mind and strength and loving your neighbor as yourself are the two most important things in life (the highest commandment of the Hebrew Torah, according to Jesus; see Gospel of Mark chapter 12, verses 28–34). St. Augustine summed this up when he wrote “he loves God and does what you want”.
The apostle Paul glorified love as the most important virtue of all. Describing love in the famous poetic interpretation of 1 Corinthians, he wrote: “Love is patient, love is kind. It does not envy, it does not boast, it is not proud. It is not rude, it is not selfish, it does not get angry easily. ., does not bear grudges. Love does not delight in evil, but rejoices in the truth. It always protects, always trusts, always hopes and always perseveres “. (1 Corinthians 13: 4-7, NIV)
