David’s actions—or more precisely, his lack of action due to his great restraint—must have been shocking to Saul. What would he have done had the situation been reversed? In that moment of being confronted by David’s act of mercy, Saul experienced a moment of clarity. He recognized that God’s hand was surely on David, and he left him in peace (though this would not last; see 1 Sam. 26).
This is the power of God working in and through His people. God has called us to live counterculturally, to live differently and express the fragrance of Christ in a world permeated by the stench of sin and death. What we do—or rather, what God does through us—reinforces the truth of the gospel message we share. Does the gospel need our actions for it to be effective? By no means! But when we live in such a way that shows that the gospel is not merely academic, that it transforms us to live like Christ, we display the beauty of the message we proclaim.
In what ways is God changing you? In what ways do you see the need for Him to continue to change you?
