Psalms 91:5 Thou shalt not be afraid for the terror by night; nor for the arrow that flies by day; 6 Nor for the pestilence that walketh in darkness; nor for the destruction that wastes at noonday.
Fear has the potential to crystalize faith, and if it is allowed to run riot, it could freeze hope and trust in God, and could cause, even the most conscientious Christian to make a wrong decision on the spur of the moment, which he or she may never have made under more favorable circumstances. Thus, the Lord encourages our faith to shine brightly when the going gets rough, and we must remember to take hold of the arm of Omnipotence, even when the giants in the land might loom larger than life.
In fact, fear is the favorite tool of satan to try to drive the Christian to do the unthinkable. When fear went unbridled and unrestrained, in the experiences of David, it caused him to play the mad man, and in doing so, he let his spittle run down his beard, even as he scrabbled unintelligible writings on the wall. The situation was that David had fled to the Philistines, in order to escape from Saul.
Whilst in their company someone recognized him as the one who had recently killed Goliath, and when David realized that they knew who he was, he went into a full blown panic mode, resorting to stratagem and acting a lie, in order to save himself from what he saw as certain retribution.
1st Samuel 21: 11 And the servants of Achish said unto him, Is not this David the king of the land? did they not sing one to another of him in dances, saying, Saul hath slain his thousands, and David his ten thousands? 12 And David laid up these words in his heart, and was sore afraid of Achish the king of Gath.
May The Lord add His blessing to the study of His word. God bless!
