Love is patient, love is kind and is not jealous; love does not brag and is not arrogant, does not act unbecomingly; it does not seek its own, is not provoked, does not take into account a wrong suffered, does not rejoice in unrighteousness, but rejoices with the truth; bears all things, believes all things, hopes all things, endures all things.
Love never fails; but if there are gifts of prophecy, they will be done away; if there are tongues, they will cease; if there is knowledge, it will be done away. For we know in part and we prophesy in part; but when the perfect comes, the partial will be done away. When I was a child, I used to speak like a child, think like a child, reason like a child; when I became a man, I did away with childish things. For now we see in a mirror dimly, but then face to face; now I know in part, but then I will know fully just as I also have been fully known. But now faith, hope, love, abide these three; but the greatest of these is love.
1 Corinthians 13 (NASB)
I believe that everyone should take this chapter of the Bible to heart, literally. There are many criticisms of Christians and the Bible, but honestly, these basic concepts of love are what all religions and philosophies are about. Christians who condemn and judge others are merely picking and choosing the parts of the Bible they want to adhere to, and ignoring the core message. Most of the time, we should just get back to the basics of humanity and humility.
