Daniel 3:27
And the satraps, administrators, governors, and the king’s counselors gathered together, and they saw these men on whose bodies the fire had no power; the hair of their head was not singed nor were their garments affected, and the smell of fire was not on them.

This is how God saves. Those whom He delivers are not destroyed, they are not defiled by the world or its fiery trials. He is with them in the fire and cleanses them from any hurt done to them by sin. They appear without spot or wrinkle or any such thing. This appears to the men of the world as well and if they are perceptive they will see that God is among them of a truth…and if not they will certainly know when the sons of God are revealed with Christ on that last day.
