Lots of people today would never consider themselves guilty of idolatry as far as it is spelled out in the Ten Commandments, but by reducing God to some benevolent "man upstairs" whose only attributes are love and tolerance, and who could not care less about sin, they truly have transgressed God's commandment. They have created a god in their mind who does not actually exist and will on the day of judgment, not be able to offer them any help.
