The Ephesians were told that they "were without Christ" and they are "now in Christ Jesus".
(Eph 2:11) Therefore remember that you, the nations, in time past were in the flesh, who are called Uncircumcision
by that which is called the Circumcision in the flesh made by hands;
(Eph 2:12) and 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 the world
(Eph 2:13) But now in Christ Jesus
you who were once afar off are made near by the blood of Christ.
They were positioned in Christ when they believed "in Christ". Once that's accomplished then we are positioned "in Christ" in the heavenlies, beyond space and time, making Eph 1:4 correct in saying that God chose us "in Him" before the foundation of the world.
