To often we believe that God is a "good God." Which He is, of course, but He is not all bunny rabbits and sweetness as some want to think of Him ~ He is often fierce and mighty, sharp and straight forward. What He says He means.
C. H. Spurgeon said, “People are disturbed and troubled by the real gospel: under the false gospel they can sleep into destruction. Bring out the sword: it is made to wound; let it exercise its salutary sharpness.”
The sword of God’s word cuts at sin to the very depths of the soul. "For the word of God is living and active and sharper than any two-edged sword, and piercing as far as the division of soul and spirit, of both joints and marrow, and able to judge the thoughts and intentions of the heart. And there is no creature hidden from His sight, but all things are open and laid bare to the eyes of Him with whom we have to do" (Hebrews 4:12-13).
