1 Samuel 2:9

He will guard the feet of His saints, but the wicked shall be silent in darkness.  For by strength no man shall prevail.  

The Lord is our guide, and He guards His saints in which way they should go.  Jesus will keep us from evil as we listen to the inward witness.  Man shall never prevail against God or His saints.  As our focus remains on God and the word, we are reminded to be of good cheer because Jesus has overcome the world.
