Rom 11:23 And they also, if they abide not still in unbelief, shall be graffed in: for God is able to graff them in again.
All who are not in Christ are strangers and aliens from the commonwealth of Israel. This speaks of Christ, the true Israel of God and His Body for Jesus Christ identifies with His Body as being one in and with Him.
Eph 2:12 That at that time ye were without Christ, being aliens from the commonwealth of Israel, and strangers from the covenants of promise, having no hope, and without God in the world:
We are all made nigh or brought close, by being grafted into the Olive tree, the Vine, Jesus Christ.
Eph 2:13 But now in Christ Jesus ye who sometimes were far off are made nigh by the blood of Christ.

Eph 2:14 For he is our peace, who hath made both one, and hath broken down the middle wall of partition between us
Eph 2:22 In whom ye also are builded together for an habitation of God through the Spirit.
Through the Spirit we are God's habitation.
The Hope of Israel
