“And you He made alive, who were dead in trespasses and sins, in which you once walked according to the course of this world, according to the prince of the power of the air, the spirit who now works in the sons of disobedience, among whom also we all once conducted ourselves in the lusts of our flesh and of the mind, and were by nature children of wrath, just as the others.
“But God, who is rich in mercy, because of His great love with which He loved us, even when we were dead in trespasses, made us alive together with Christ (by grace you have been saved), and raised us up together, and made us sit together in the heavenly places in Christ Jesus, that in the ages to come He might show the exceeding riches toward us in Christ Jesus. For by grace you have been saved through faith, and that [is] not of yourselves; it is the gift of God, not of works, lest anyone should boast. For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand that we should walk in them.
“Therefore remember that you, once Gentiles in the flesh—who are called ‘Uncircumcision’ by [those who are called] the ‘Circumcision’ made in the flesh by [their own] hands—that at that time you were without Christ, being aliens from the commonwealth of Israel and strangers from the covenants of promise, having no hope and without God in [your] world. But now in Christ Jesus you who once were far off have been brought near by the blood of Christ.
“For He Himself is our peace, who has made both [the Uncircumcised and the Circumcised] one, and has broken down the middle wall of separation, having abolished in His flesh the enmity, that is, the law of commandments contained in ordinances, so as to create in Himself one new man (humanity) from the two, thus making peace, and that He might reconcile them both to God in one body through the cross, thereby putting to death the enmity. And He came and preached to you (the uncircumcised) who were far off and to those (the circumcised) who were near. For through Him we both have access by one Spirit to the Father.
“Now, therefore, you (the uncircumcised) are no longer strangers and foreigners, but fellow citizens with the saints and members of the household of God, having been built on the foundation of the apostles and prophets, Jesus Christ Himself being the chief cornerstone, in whom the whole building, being fitted together, grows into a holy temple in the Lord, in whom you also are being built together for a dwelling place of God in the Spirit.”
There is so much glory in understanding the context. Read this passage slowly, and see what you find! Notice that Paul isn’t trying to “convert” but simply stating the truth of what already happened to them.
