Ephesians 1:11
In him we were also chosen, having been predestined according to the plan of him who works out everything in conformity with the purpose of his will,12in order that we, who were the first to hope in Christ, might be for the praise of his glory.
1 Peter 2:6
For in Scripture it says: "See, I lay a stone in Zion, a chosen and precious cornerstone, and the one who trusts in him will never be put to shame."
1 Peter 1:18For you know that it was not with perishable things such as silver or gold that you were redeemed from the empty way of life handed down to you from your forefathers, 19but with the precious blood of Christ, a lamb without blemish or defect. 20He was chosen before the creation of the world, but was revealed in these last times for your sake. 21Through him you believe in God, who raised him from the dead and glorified him, and so your faith and hope are in God.
Romans 7:4
So, my brothers, you also died to the law through the body of Christ, that you might belong to another, to him who was raised from the dead, in order that we might bear fruit to God.
Romans 12:5
so in Christ we who are many form one body, and each member belongs to all the others.
1 Corinthians 12:12
The body is a unit, though it is made up of many parts; and though all its parts are many, they form one body. So it is with Christ.
1 Corinthians 12:27
Now you are the body of Christ, and each one of you is a part of it.
One in Christ
11Therefore, remember that formerly you who are Gentiles by birth and called "uncircumcised" by those who call themselves "the circumcision" (that done in the body by the hands of men)— 12remember that at that time you were separate from Christ, excluded from citizenship in Israel and foreigners to the covenants of the promise, without hope and without God in the world. 13But now in Christ Jesus you who once were far away have been brought near through the blood of Christ.
14For he himself is our peace, who has made the two one and has destroyed the barrier, the dividing wall of hostility, 15by abolishing in his flesh the law with its commandments and regulations. His purpose was to create in himself one new man out of the two, thus making peace, 16and in this one body to reconcile both of them to God through the cross, by which he put to death their hostility. 17He came and preached peace to you who were far away and peace to those who were near. 18For through him we both have access to the Father by one Spirit.
Ephesians 2:19Consequently, you are no longer foreigners and aliens, but fellow citizens with God's people and members of God's household, 20built on the foundation of the apostles and prophets, with Christ Jesus himself as the chief cornerstone. 21In him the whole building is joined together and rises to become a holy temple in the Lord. 22And in him you too are being built together to become a dwelling in which God lives by his Spirit.
Ephesians 3:6
This mystery is that through the gospel the Gentiles are heirs together with Israel, members together of one body, and sharers together in the promise in Christ Jesus.
It was Jesus body that was chosen before the foundation the only way we were chosen was by being in it. None of you including myself were worthy of being chosen, but being in Jesus where God doesn't see you but His Son. You in of yourself can never be chosen, but only in Christ could you be. Don't think highly of yourself but highly of Him.
