Become a dwelling in which God lives by his Spirit

Ephesians 2:11-22
Now in Christ Jesus you who once were far away have been brought near through the blood of Christ.
For he himself is our peace, who has made the two one and has destroyed the barrier, the dividing wall of hostility敵對, by abolishing in his flesh the law with its commandments and regulations.
We are no longer foreigners and aliens, but fellow citizen with God's people and member of God's household, built on the foundation of 1)the apostles and 2)prophets, with 3)Christ Jesus himself as the chief cornerstone.
In him the whole building is joined together and rises to become a holy temple in the Lord. -- the church
In him you too are being built together to become a dwelling in which God lives by his Spirit.
Why?
In the ancient world Jews were separated from Gentiles by racial, religious, cultural and social barriers. The Jews were God's chosen people, near to him; the Gentiles were sinful heathens, far off, If Christ could bring these two together, there is no human gulf too great for him to bridge His death on the cross is the one means of peace with God for all people, without distinction, those who are near and those who are near and those who are far off.
When we became a Christian, we are fellow citizen with God's people, the citizen of the God's kingdom forever. Don't have to pay money stay in some place for a few years like in America.
Our faith are built on the foundation of the apostles and prophets, they preached God's words and on the foundation of Jesus Christ as chief cornerstone- the beginning. The Spirit of God is dwelling in us teach me and guides me.
How?
Keep my body Holy and my mind withe the Lord, let the Holy Spirit may dwelling in me. Read His words everyday to remind me, pray for myself be pleased before the Lord.
