“...purify your hearts, ye double minded” – James 4:8
People who are Christians and yet live different lifestyles in secret are guilty of duality: A double standard life. It is the art of having two personalities or two natures embodied in one person.
A person manifests duality when he has one lifestyle displayed in public, and another one shown in private. He exhibits one behaviour pattern in public to impress the people around. He shows another behaviour secretly. For those who claim to be Christians, one lifestyle is displayed in church, and the other, outside of church. Duality encourages the spirit of hypocrisy, the spirit of lies and the spirit of self deception.
There are some who are very nice in public, but extremely nasty at home. Their spouses and children know them to be very impatient and abusive, but those outside the home see them as the sweetest people on earth.
Many husbands have complained to me that they cannot help but notice the humility and gentleness, which their wives reserve for their pastors and outsiders. This makes them feel that their spouses respect and love their pastors more than their own husbands.
Such a wife or husband has a dual life. They have two different natures: the nasty nature, which they display in private (usually those close to them have to endure it), and the nice nature, which they display openly
