(1 Corinthians 13:4-8 NIV) Love is patient, love is kind. It does not envy, it does not boast, it is not proud. {5} It is not rude, it is not self-seeking, it is not easily angered, it keeps no record of wrongs. {6} Love does not delight in evil but rejoices with the truth. {7} It always protects, always trusts, always hopes, always perseveres. {8} Love never fails. But where there are prophecies, they will cease; where there are tongues, they will be stilled; where there is knowledge, it will pass away.

What's described is the love we're supposed to have and show as Christians. It's not limited to the kind of love we should have towards our spouse.
