Your greatest threat to your faith is going to come from yourself. When you suffer misery, hunger, sickness and watch those you love suffer and get beaten/arrested or killed - just about everything you assumed about being a Christian gets tossed up into doubt and every emotion you have will be tested to it’s breaking point. You begin to get angry with God.
We have no experience with suffering such things when persecution and privation become institutionalized by society and the ruling classes.
But it’s something we need to be mindful of when opposing evil and living as we should in a society declining into wickedness and tyranny.
I got just a small taste of that - and I nearly lost my faith.
I have experienced some of what you talk about and I know that I am just a man and full of emotion and the illogic of anger. I also know that turning the other cheek does not mean that we have to let the Lions eat us. I pray for strength every day.
LUKE 22:36
King James Bible
Then said he unto them, But now, he that hath a purse, let him take it, and likewise his scrip: and he that hath no sword, let him sell his garment, and buy one.
