Why does God choose some for grace and not others?

The question of why God chooses some for grace while others do not receive it is rooted in His sovereign will. According to Romans 9:10-13, God's purpose of election is not based on works or actions but solely on His call. This underscores the belief that grace is a part of God’s eternal plan, typically referred to as unconditional election. God, in His wisdom, has chosen to show mercy to some while hardening others, demonstrating that grace is a sovereign act of God’s love, independent of human merit or free will.
