What lessons can Christians learn from David's mercy towards Saul?

David's decision to spare Saul, even when he had the opportunity to kill him, serves as a profound example of mercy and trust in God's providence. Despite Saul's attempts to take David's life, David refrained from acting out of self-interest, illustrating the principle that vengeance belongs to the Lord. This act of mercy reflects the character of Christ, who forgave His enemies and extends grace to sinners. Believers are called to emulate this mercy in their own lives, trusting that God will ultimately execute justice according to His perfect plan.
