爱是恒久忍耐，又有恩慈；爱是不嫉妒；爱是不自夸，不张狂， Love is patient, love is kind. It does not envy, it does not boast, it is not proud. 不做害羞的事，不求自己的益处，不轻易发怒，不计算人的恶， It does not dishonor others, it is not self-seeking, it is not easily angered, it keeps no record of wrongs. 不喜欢不义，只喜欢真理； Love does not delight in evil but rejoices with the truth. 凡事包容，凡事相信，凡事盼望，凡事忍耐。 It always protects, always trusts, always hopes, always perseveres. 爱是永不止息。 (哥林多前书 13:4-8 ) Love never fails. (Corinthians 13:4-8 NIV)
