What most modern Western people (including many Christians) are asking for in the name of freedom’ is in fact a new slavery, when they attempt to secularize the public sphere and pursue freedom without the Lordship of Christ. To object to this by saying that non-believers are not accountable to God’s covenant law (moral law) is finally to say that we have no basis for presenting the gospel to the unbeliever – since Scripture defines sin as lawlessness and only lawbreakers need the gospel!
