Every human is a hypocrite. Say you were to stand outside a busy shopping mall in order to survey the broad population about their moral framework. Ask people what they believe to be right or wrong, what their primary moral guidelines are, and what they believe evil to be you would certainly get a great deal of variety. However, if you followed up that survey with a question about whether they have perfectly kept their own moral framework, every honest participant would need to admit that they broke their own moral code.
Culturally, we live in a world governed by rules and regulations. Some of these laws are better and more biblical than others, but we are surrounded by a dense forrest of litigiousness. But though we have our rules, we commonly break those rules while insisting we are keeping the spirit of those rules.
Yet if we really took a long and honest look at ourselves, we not only are breakers of the letter of the law, we are breakers of the spirit of the law. Our hypocrisy is deep and wide. It transcends lines of liberal and conservative, male and female, and national borders. It is the condition of man. He holds up standards for others that he himself does not attain to. You are, on your own, blackmailed by your own moral inconsistency.
This is why the new birth which is offered to us in Christ is of absolute necessity. The Christian is one who acknowledges their great sinfulness, but not to bemoan it or wallow in it, but to confess it, be rid of it through the forgiveness which the Father gives, and to overcome it by the Spirit’s power at work in us. Only by honest confession is the blackmail of your moral hypocrisy rendered powerless.
