Why does God give grace to some and not to others?

The distribution of God's grace is a matter steeped in His sovereignty and divine will. Ephesians 1:5-6 illustrates this concept, stating, 'Having predestinated us unto the adoption of children by Jesus Christ to himself, according to the good pleasure of his will, to the praise of the glory of his grace.' This indicates that God's choice to grant grace is not based on any foreseen merit on our part, but solely on His own purpose and grace. This aligns with the teaching of sovereign grace theology, which emphasizes that God has the right to extend grace as He sees fit, ultimately for His own glory and the good of His elect.
