trophies of grace

Ephesians 2:7
... so that in the coming ages he might show the immeasurable riches of his grace in kindness towards us in Christ Jesus.

Our salvation shows how gracious God is. We are trophies of his grace. The immeasurable riches of his grace are demonstrated by his kindness towards us. The fact that God would love us and save us and accept us shows how wonderful his grace is. Do our lives show off God's grace? Or do we give off a message of self-improvement via "christianity"?
