The Letter to the Galatians really can be summed up in this way: a Christian is not one who does this and that and another thing which is prescribed to be done; a Christian is not one who refrains from doing this and that and another thing because they are forbidden; a Christian is not one at all who is governed by the externalities of a way of life, an order, a legalistic system which says, You must, and You must not, a Christian is comprehended in this saying, It pleased God to reveal His Son in me (Gal. 1:15-16).
