'David...selected five...stones from the brook.' Here are five stones you can use: 1) The stone of past successes. David remembered the way God had helped before saying, 'God, who delivered me from the...lion and...bear, will deliver me...' (1 Samuel 17:37). The human memory usually hangs on to bad memories longer than good ones! So, why not get a notebook to keep track of the 'marvelous works...He has done' (1 Chronicles 16:12) 2) The stone of prayer. 'Prayer is essential in this ongoing warfare' (Ephesians 6:18); you can't win without it. For many years David was on the run from crazy king Saul but he kept praying to God who he called his 'defense and refuge' (Psalm 59:16 NKJV) 3) The stone of honor. Lots of arrogant people like to diss God but Christians are concerned with defending his honor. David's defend it by killing Goliath and proving 'There is a God in Israel' (1 Samuel 17:46). Involving God in your situation gives an opportunity for His grace and power to shine. 4) The stone of passion. David was the only person in the nation with more passion than wisdom! Fighting Goliath was a stupid idea but God responded to David's passionate heart and gave him victory. Sometimes it's good to let your heart rule your head. 5) The stone of preparation. You have to ask why David picked five stones. It was probably because he didn't know how many he'd need to do the job! 'It ain't over 'til it's over,' so be prepared, victory may not be instant but with God's help it will come in time.
