I would gain nothing, unless I loved others. Love is kind and patient, never jealous, boastful, proud, or rude. Love isn't selfish or quick tempered. It does not keep a record of wrongs that others do. Love rejoices in the truth, but not in evil.
Love is always supportive, loyal, hopeful, and trusting.
Everyone who prophecies will stop, and unknown languages will no longer be spoken. All that we know will be forgotten. We don't know everything, and our prophecies are not complete. But what is perfect will someday appear, and what is not perfect will then disappear. When we were children, we thought and reasoned as children do.
