The First Epistle to the Corinthians is a book of the Bible in the New Testament. 1 Corinthians is a letter from Paul of Tarsus and Sosthenes to the Christians of Corinth, Greece. This epistle contains some of the best-known phrases in the New Testament, including (depending on the translation) "without love, I am nothing" (13:1) and "when I was a child, I spoke as a child, I felt as a child, I thought as a child" (13:11). Paul turns the hearts of Christians from selfish factionalism to selfless service of others in love.
