“Of course we have our spiritual liberties. But when we find ourselves unable to enjoy the Christian life without our liberties, then we have become enslaved to them. There is, for example, presumably no built-in evil about owning a new car, or living in pleasant house, or enjoying various foods, spending time in various pursuits, or with certain kinds of people. But when we cannot be content without them; when we simply must have them—they are no longer our liberties, but our chains. The Christian should develop in Christ a sensitivity to those things to which he will most readily allow himself to be brought into bondage. ‘Will this enslave me?’ will be a question never far from his thinking. ‘I will not be mastered by anything’ (2 Tim. 1:7) is a good motto text for the man who has received a spirit of self-discipline.” (Sinclair Ferguson)
