To love a person, no matter how they may disappoint you, to love them in spite of their faults, to love them when they makes choices that aren't approved of, that is unconditional love.
We all desire to be loved unconditionally. The mormon church teaches a different kind of love. It teaches a conditional love. If you don't do what god expects, he will withdraw his love. If you leave the mormon church, you are labeled an apostate and your family members are then told they cannot associate with you and then be worthy to enter the mormon temple.
Here is a quote from one of the authorities in the mormon church:
While divine love can be called perfect, infinite, enduring, and universal, it cannot correctly be characterized as unconditional. The word does not appear in the scriptures. On the other hand, many verses affirm that the higher levels of love the Father and the Son feel for each of us—and certain divine blessings stemming from that love—are conditional
"The full flower of divine love and our greatest blessings from that love are conditional-predicated upon our obedience to eternal law. I pray that we may qualify for those blessings and rejoice forever." - Russell M. Nelson, "Divine Love," Ensign, Feb. 2003, page 20
I will take unconditional love over conditional love any day, mormon church.
