“But far be it from me to boast except in the cross of our Lord Jesus Christ, by which the world has been crucified to me, and I to the world. For neither circumcision counts for anything, nor uncircumcision, but a new creation” (Galatians 6:15-16, ESV).
The Apostle Paul says the cross that crucified Christ has also crucified the world to him as a result of his faith in Christ.
Paul is saying that the worldly system of this present life has no power to attract him; it no longer has any appeal to Paul; in other words, in Christ he is dead to the world.
Similarly, Paul is dead to the desires and attractions of the world, for Christ is now his new master and no other.
So, when we get completely connected with Christ, then we become totally disconnected to the world.
“Therefore, if anyone is in Christ, he is a new creation. The old has passed away; behold, the new has come” (2 Corinthians 5:17, ).
