Sometimes love is truly tested when conflicts or misunderstandings cause walls to be put up, not to keep you out, but to see if your love really has enough strength to knock the walls down.
[1 Corinthians 13:1-7]
If I speak with the languages of men and of angels, but don't have love, I have become sounding brass, or a clanging cymbal. If I have the gift of prophecy, and know all mysteries and all knowledge; and if I have all faith, so as to remove mountains, but don't have love, I am nothing. If I dole out all my goods to feed the poor, and if I give my body to be burned, but don't have love, it profits me nothing.
Love is patient and is kind; love doesn't envy. Love doesn't brag, is not proud, doesn't behave itself inappropriately, doesn't seek its own way, is not provoked, takes no account of evil; doesn't rejoice in unrighteousness, but rejoices with the truth; bears all things, believes all things, hopes all things, endures all things.
