Genesis 4:7
No soldier goes to the field of battle not knowing the enemy against which he must fight. The Christian wears the badge of many titles—the badge of a son, the badge of a servant; the badge of a disciple and the badge of a friend. The badge of priest and king, yea also of saint and elect. Yet, amidst this decoration of honorary attire, there’s one badge that I left off to mention, which without, his uniform would be incomplete. What badge is this to which I refer? It is the badge of a soldier — a soldier of Jesus Christ!!
Tell me of the foe against which you war? Tell me of the hardships endured on account of this warfare? Where are your scars, where are your victories? Where are our medals of honour...where are your stripes? What is the foe to which I refer? “...sin lieth at the door. And unto thee shall be his desire, and thou shalt rule over him” (Gen. 4:7).
