Saul continues to chase David, but David chooses not to harm him when they cross paths in a cave. This illustrates the concept of grace—doing kind things for those who don't deserve it. But an even greater example of grace is Jesus, who died for our sins so we can have eternal life with God. Saul's response to David's grace is surprising; he asks for forgiveness and praises David. This teaches us to love and show kindness even to our enemies, as Jesus instructs. David's strength to show grace came from spending time with God in the cave.
