"...He will sit as a refiner's fire or launderer's silver..." -- Malachi 3:2,3.
All of us begin our lives dirty, and sinful. No one is able to escape the second death without Jesus. The image of Christ mining us from the ground and being refined, having all the impurities being taken away has been a breath-taking portrayal of Jesus in my mind. The process of refining silver, or any metal is a lengthly process for the metal to become pure. Christ who has begun to refine you will refine you to completion (Php 1:6). As Christians we can't refine ourselves because we are the ones who are in need of the refining. Jesus is the only one who has the power to refine you to the purest state. We know refining takes a lot of heat, please let Jesus refine you, so you are not burned in the fire forever.
