Commonplace Virtue? "But to those of you who will listen, I say: Love your enemies, do good to those who hate you, bless those who curse you, pray for those who mistreat you. If someone strikes you on one cheek, turn to him the other also. And if someone takes your cloak, do not withhold your tunic as well. Give to everyone who asks you, and if anyone takes what is yours, do not demand it back. Do to others as you would have them do to you.
If you love those who love you, what credit is that to you? Even sinners love those who love them. If you do good to those who do good to you, what credit is that to you? Even sinners do the same. And if you lend to those from whom you expect repayment, what credit is that to you? Even sinners lend to sinners, expecting to be repaid in full.
But love your enemies, do good to them, and lend to them, expecting nothing in return. Then your reward will be great, and you will be sons of the Most High; for He is kind to the ungrateful and wicked. Be merciful, just as your Father is merciful." - Jebus
The problem with morality, is that we're all big fat hypocrites, and we don't know how to change the world, by being the change we want to see in the world, by acting towards the wicked as we wish them to act, to embodying, rather than mouthing our virtues.
I am far from perfect, and I even go further than that and say that no one is even good, but this too is quoting Jesus: "Why do you call me good?" Jesus answered. "No one is good--except God alone."
Another way that truth telling facilitates the undermining of your own wickedness, is that if you don't pretend to be only helpful, only benevolent, only righteous and good, people then may guard against you as well.
