The battle between David and Goliath isn't really about a little guy and a big giant. Instead, it's about a big challenge and an even bigger God. Faithfulness to God required David to do something far beyond his own ability. Faith is like that for us, too. Eventually, we'll encounter a challenge, a decision, or a change that is just too risky or costly for us. It's in those moments that we must trust in God and do what honors Him.
