Hello,
Larisa, Bible verses you quote are great words about love.

Your great writer Tolstoy wrote a lot about love in his books. Forgive if bad translations.

“Only people who are capable of loving strongly can also suffer great sorrow, but this same necessity of loving serves to counteract their grief and heals them.”
“When you love someone, you love the person as they are, and not as you'd like them to be.”
“Love is life. All, everything that I understand, I understand only because I love. Everything is, everything exists, only because I love."
― Leo Tolstoy

"For me love is the thing that causes the greatest joy, but can also cause the greatest pain, but I would rather not live without it."
