Why is the covenant important in the story of Mephibosheth?

The importance of the covenant in the story of Mephibosheth is crucial as it represents the basis of David's kindness. David's covenant with Jonathan—a promise of loyalty and kindness—was the reason he sought out Mephibosheth to extend favor and restore his heritage. This act of kindness reflects God's covenant of grace towards His people through Christ. Just as Mephibosheth benefits from the actions taken on behalf of Jonathan, believers receive grace and salvation based on the covenant established by Christ's sacrifice, as seen in Hebrews 8:6.
