love conquers all

Love conquers all is another way to say that love is vitally important in life and that when you have love, it makes everything else seem less important. By saying it conquers all, you are showing that loving or being in love can get past any of the typical issues in life, no matter what kind of trials and tribulations come your way. It is often used as a motivational tool for people who are in love and are dealing with troubles but rely on each other to get through it.
