I wonder about the effectiveness or validity of a Christian who is never spiritually attacked (and no I'm not judging, that is Gods place)
You get hit because you are a threat to Satan and ONLY by what God will allow because in His wisdom He knows it will make you stronger etc and even more good will come out of it.
I don't believe if you are following Jesus that you won't be a threat or persecuted in some way.
No one can rejoice in a normal way when these things happen. We are told to rejoice IN THE LORD ( knowing our place in Christ is assured and that we are pleasing Him, the peace that passes all understanding)
So take heart, if God be for us, who can be against us?
