. . . in order that in the coming ages He might show the incomparable riches
of his grace, expressed in his kindness to us in Christ Jesus.
(Ephesians 1:7 NIV)
God could have chosen a plethora of ways to exhibit His grace to the world. God could have demonstrated His grace by writing it in the celestial realm. He could have placed grace in the cavity of the Grand Canyon, or chiseled grace in the side of a mountain. Instead God put grace in our hearts so that humanity would be on display, revealing His amazing grace. We then become monuments of that grace, channels through whom the truth of that grace is made known to all creation.
