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
