It’s been a problem since the first church council (recorded in Acts 15); for some reason humans get hung up on externals.  We have a deep propensity for evaluating people, including ourselves, based upon what we do or do not do.  Technically, legalism is the subject addressed in the New Testament book of Galatians.  There we learn that legalism in the strictest sense is the teaching that we cannot be right with God apart from keeping the law.  Paul referred to that as “another gospel of another kind.”  He wrote to the Ephesians that salvation is not of works because we would boast about it.  Salvation is by grace alone, through faith alone, made possible by Christ alone and for the glory of God alone!  However, over the years, people who believe that statement have still made lists of what they deemed to be appropriate and inappropriate behaviors including all kinds of things ranging from what one eats and drinks to forms of entertainment to what Bible version one uses.   That has often been referred to as legalism but it is only “practical legalism.”  By that I mean having to do with everyday practice not destiny.  For many years there were a lot of “don’ts” on that list for the members of evangelical (and especially fundamental) churches.  In spite of the fact that Jesus talked about the development of one’s heart, we still became focused on the externals.  Sadly, many people still miss the point but have gone in the ditch on the other side of the road.  Now, it seems many boomers and millennials have taken the things on the list and decided to practice them “since the Bible doesn’t forbid them…” as a new test of one’s spirituality.  Our freedoms in Christ and “under grace” are championed on Facebook and in conversations as if this is new revelation.  My fear is not the liberty, it is that we are still focused on the externals!  The doing and not doing should not be the central issue.  The heart of the matter is the heart.   The reader will say, “What we do is reflective of the heart.”  True and False.  Sometimes what we do is to hide the heart.  Jesus certainly cares about what we do and don’t do; this is fairly obvious in the Sermon on the Mount.  The principal matter however, is what we are becoming from the inside out.  What kind of people are we becoming?  What kind of person do you want to be when you grow up?  It sure would be amazing if we could get committed to that.
