Ephesians 3:2

Ephesians 3:2 If indeed you have heard of the stewardship of the grace of God which was given to me for you,

The stewardship of the grace is the dispensing of the grace of God into God's chosen people for the producing and building up of the church. Out of this stewardship comes the ministry of the apostle, who is a steward in God's house, ministering Christ as God's grace to God's household.

Ephesians 2:22

Ephesians  2:22 In whom you also are being built together into a dwelling place of God in spirit.

Verse 22 says that we are being built together into a dwelling place of God in spirit. The spirit here refers to the believers' human spirit indwelt by God's Holy Spirit. God's Spirit is the Dweller, not the dwelling place. The dwelling plce is in the believers' spirit. God's Spirit dwells in our spirit. Therefore, the dwelling place of God is in our spirit.
