Loving God with our whole being and neighbor as our self is what sets Christians apart.  Loving God and neighbor in this manner is both the way of holiness and the true expression of it.  It is this that prepares our hearts for the coming of our Lord Jesus, “with all of his saints.”  It is this that makes us “saints” (holy ones) who will be in that company with Him and “with all the saints” when He comes.

 “Now may our God and Father Himself and Jesus our Lord direct our way to you; and may the Lord cause you to increase and abound in love for one another, and for all people, just as we also do for you; so that He may establish your hearts without blame in holiness before our God and Father at the coming of our Lord Jesus with all His saints.”  1 Thessalonians 3:11-13 (NASB)
