What does the Bible say about kindness and grace?

In 2 Samuel 9, we see David seeking out the remaining members of Saul's household to show kindness for Jonathan's sake. This act reflects the greater kindness and grace that God shows to His people. The covenant between David and Jonathan mirrors the covenant of redemption made between the Father, the Son, and the Holy Spirit, whereby God extends grace to the undeserving. In Ephesians 1:4-5, we learn that God chose us in Christ before the foundation of the world, showcasing His sovereign grace and kindness toward those who are often likened to Mephibosheth—unworthy and helpless.
