Ask any of 300 million or more Christians who suffer systematic oppression, deprivation, harm every day for the privilege of bearing the name "Christ-ian"
2 Corinthians 11:22-30. "far greater labors, far more imprisonments, with countless beatings, and often near death. 24 Five times I received at the hands of the Jews the forty lashes less one. 25 Three times I was beaten with rods. Once I was stoned. Three times I was shipwrecked; a night and a day I was adrift at sea; 26 on frequent journeys, in danger from rivers, danger from robbers, danger from my own people, danger from Gentiles, danger in the city, danger in the wilderness, danger at sea, danger from false brothers; 27 in toil and hardship, through many a sleepless night, in hunger and thirst, often without food,[b] in cold and exposure."
1 Peter 4:1 "Since therefore Christ suffered in the flesh, arm yourselves with the same purpose, for whoever has suffered in the flesh has ceased from sin, so as to live for the rest of the time in the flesh no longer for human passions but for the will of God."
My position is that the power of the living Christ (through the Holy Spirit in the body) works effectively through "dead" vessels - dead to the stimulus of the world/flesh/devils. I take Romans 8:13 and related supporting verses quite seriously - that followers of Christ are marked by separation from what I call the "false fuel of Flesh", and switch-over our tanks to running on "by the Spirit" energy. It is a long discussion and a longer walk, but the only way an American, I think, can get a taste of it is by devoting large chunks of time, habitually, to the Lord alone, "practicing righteousness" and begging for the "Granting" of true repentance. It does not come by accident. The path is shortened considerably by capture, torture, the loss of all worldly means, etc via persecution, war, famine, etc.
The GOOD NEWS, unless one is a cessationist, is that the Holy Spirit will intensely work in such people, channeling through them the proof of Christ's living presence. The most alarming, arresting proof, (though certainly not the Only) is radically changed lives, lived on a long walk unto death. That is a work of the spirit, not mental.
