We are of God: he that knoweth God heareth us; he that is not of God heareth not us. Hereby know we the spirit of truth, and the spirit of error. I John 4:6

Those who do not know Him cannot possibly understand the path the saint walks on. We are on a road that leads home, Phillipians 3:20. They are already home in this world. We face many trials and tests in this world, but we patiently endure, knowing that they are only temporary, and are preparing us for an eternal weight of glory, beyond all comparison, II Corinthians 4:16-18. They also have trials, but for those who do not know Him, there is no hope beyond this world. 

This results at least in misunderstanding, and, in many cases, violent confrontation. Why is there such offense? I suggest that our very presence in this world reminds them of their future. This is why the enemies in the spiritual realm persecute us. They also know that their future is bleak. The Light that is in us scatters the darkness. So they hide. Or strike back at us. We must be aware of the battle going on around us.
