Psalm 144

David the warrior took up his harp and played a new song (vs 9). A song about God's victory and provisions. David looked back on his life and saw how God prepared him to fearlessly lead the army of Israel into battle.  God proved his faithfulness to David through conflict and abundance.  Just as God delivered David from the savage Philistines so will he bring us through the ravages of our moral questions in the 21st century.
It took me about 2 minutes to read this passage.
