Hi @iuliatsurkan! Love is many things indeed. But it is not all things. It is not pain nor sorrow. Love is ultimately the greatest gift to mankind. In love there is sacrifice, in loving others with a self-less love there may be pain. But love, true love is pure.
Love is patient. Love is kind. Love is not jealous or boastful or proud or rude. Love is selfless. It is not easily irritated or angered. It is long enduring. Love hates injustices. But love promotes truth. Love protects. Love always trusts. Always hopes. Love perseveres. 1 Corinthians chapter 13 talks about this sort of love.

Love, true love from God that is birthed in the hearts of His children, by His indwelling Spirit, is pure, holy and perfect. <3
