The Liberty (and Responsibility) of the Believer

When it comes to the liberty of the believer, we are called to desire the twin qualities of peace and mutual upbuilding (Rom 14.19). I suppose that this works itself out by asking myself the question, "in regards to x, will my pursuit of it bring about peace and edify other believers?" Obviously each person's working out of the answer to that question will be different. Our problem is that we tend to do what we want and then justify it, rather than desire peace and edification and act accordingly. May we stand out, as followers of Christ, for our peacemaking spirits.
