How do we know that God's grace is truly given to us?

God's grace is a central theme in the gospel and is exemplified in the story of Mephibosheth, whom King David sought to bless for Jonathan’s sake (2 Samuel 9). This act of kindness serves as an illustration of how God extends grace and mercy to those who do not deserve it, reflecting His covenant love. The kindness of God, as David showed, is not based on merit but on His sovereign choice to show mercy, as Romans 9:16 states, 'So then it depends not on human will or exertion, but on God, who has mercy.'
