In our fallen human state, we are incapable of the perfect love that our hearts desire. Christ, however, has set the example for us and described how we should love others in 1 Corinthians 13:4-7.
"Love is patient, love is kind. It does not envy, it does not boast, it is not proud. It does not dishonor others, 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."
May we do our best to love others through this example and continue to long for this perfect love in Heaven.
