I don't think there is a verse about love being blind. Love is a very powerful emotion. It motivates much of our lives. We make many important decisions based on this emotion, and even get married because we feel that we are "in love." This may be the reason about half of all first marriages end in divorce. The Bible teaches us that true love is not an emotion that can come or go, but a decision.
There is no verse in the bible about love being blind. However, there is a verse that describes what love is in 1 Corinthians 13:4-7,13. It talks about love being patient, kind, hopeful and enduring all things.
1 Corinthians 13:4?8a (New International Version) 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 self-seeking, it is not easily angered, it keeps no record of wrongs. Love does not delight in evil but rejoices with the truth. It always protects, always trusts, always hopes, always perseveres. Love never fails. (NIV) - Proverbs 10:12 Hatred stirs up dissension, but love covers over all wrongs. (NIV) - Proverbs 13:24 Those who love their children care enough to discipline them. (NLT) - Proverbs 15:17 A bowl of vegetables with someone you love is better than steak with someone you hate. (NLT) - Proverbs 17:9 Love prospers when a fault is forgiven, but dwelling on it separates close friends. (NLT) - Proverbs 17:17 A friend loves at all times, and a brother is born for adversity. (NIV) - 'Love is blind' was made up by Shakespeare and is not a biblical quote.
