First you say no flesh involved in salvation.And you are thinking with your FLESH, thinking that Christ's Salvation is about our flesh when it is not. I have to laugh at those who just BYPASS what Apostle Paul taught in 1 Corinthians 15 about the change to the "spiritual body" at the "twinkling of an eye" on that day. God's Wrath upon the wicked will in no way harm those in Christ, and can be right in the middle of it, just like Shadrach, Meshech, and Abed-nego who were in the hot fiery furnace heated seven times hotter than necessary, and Christ was with them, and they came out of it without their clothes even smelling of smoke (Dan.3).
Then you say he will save your flesh.
Then you give verses where some ancients had their flesh saved.
