According to Calvinism, it pleased God to create the human race with the intent of withholding saving grace from the vast majority of His creation. According to Scripture, God was pleased to offer everyone salvific grace and mercy, withholding judgment until grace and mercy are utterly spurned.
“The Spirit and the bride say, Come. And let the one who hears say, Come. And let the one who is thirsty come; let the one who wishes take the water of life without cost” (Revelation 22:17).
