Focus on God's sufficiency
not human numbers or the measure of your strength
"Joab [David's general] reported the number of the fighting men to the king: In Israel there were eight hundred thousand able-bodied men who could handle a sword, and in Judah five hundred thousand.
David was conscience-stricken after he had counted the fighting men, and he said to the LORD, “I have sinned greatly in what I have done. Now, O LORD, I beg you, take away the guilt of your servant. I have done a very foolish thing.”
Before David got up the next morning, the word of the LORD had come to Gad the prophet, David’s seer: “Go and tell David, ‘This is what the LORD says: I am giving you three options. Choose one of them for me to carry out against you.’”
So Gad went to David and said to him, “Shall there come upon you three years of famine in your land? Or three months of fleeing from your enemies while they pursue you? Or three days of plague in your land? Now then, think it over and decide how I should answer the one who sent me.”
David said to Gad, “I am in deep distress. Let us fall into the hands of the LORD, for his mercy is great; but do not let me fall into the hands of men.”
So the LORD sent a plague on Israel from that morning until the end of the time designated, and seventy thousand of the people from Dan to Beersheba died....
When David saw the angel who was striking down the people, he said to the LORD, “I am the one who has sinned and done wrong. These are but sheep. What have they done? Let your hand fall upon me and my family.”
2 Samuel 24:9-15
