Love never fails. —I Corinthians 13:8a

Love is always patient and kind. It is never jealous. Love is never boastful or conceited. It is never rude or selfish. It does not take offense and is not resentful. Love takes no pleasure in other people’s sins, but delights in the truth. It is always ready to excuse, to trust, to hope, and to endure whatever comes.

Love bears all things, believes all things, hopes all things, endures all things. Love never ends. (I Corinthians 13: 7-8a ESV)

And though I have the gift of prophecy, and understand all mysteries, and all knowledge; and though I have all faith, so that I could remove mountains, but have not love, I am nothing.

If I speak with the tongues of men and of angels, but have not love, I am become sounding brass, or a clanging cymbal. And 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 have not love, I am nothing. And if I bestow all my goods to feed the poor, and if I give my body to be burned, but have not love, it profiteth me nothing.

Every time we Christians boasts about our 'Spiritual Achievements' without giving Glory to God we demolish our accumulated spiritual work (1Cor 3:13) with our own hands and we have to literally start building from scratch again. It should not surprise us Christians when on judgement day, we find that there is no work left from our side to be tested and be duly rewarded (1Cor 3:14) due to our own arrogant boasting and belittling of fellow human beings through superfluous spiritual comparisons
