Ephesians 2:7

God’s ultimate purpose is to glorify Himself. The "ages" to come include all future ages. God will use the regeneration of believers to demonstrate the wealth and richness of His grace (cf. Ephesians 1:7). Specifically His kindness toward believers as displayed in all that we have in Christ is in view. We see God’s kindness in His giving life to those who were dead in sin.

Note that Ephesians 2:1-3 describe what we were in the past, Ephesians 2:4-6 what we are in the present, and Ephesians 2:7 what we shall be in the future.
