I get that question a lot when I speak about North Korean underground believers at conferences on Christian persecution.
Hebrews 12:1-2 offers a unexpected answer: Stop sinning.
Therefore, since we are surrounded by such a great cloud of witnesses, let us throw off everything that hinders and the sin that so easily entangles. And let us run with perseverance the race marked out for us, fixing our eyes on Jesus, the pioneer and perfecter of faith. For the joy set before him he endured the cross, scorning its shame, and sat down at the right hand of the throne of God.
This is actually a corollary of rather than an alternative to Hebrews 13:3, which says, “Continue to remember those in prison as if you were together with them in prison, and those who are mistreated as if you yourselves were suffering.”
In other words, if we really were in prison with persecuted believers, one of the things we (hopefully) wouldn’t be doing is regularly giving in to our besetting sins.
So if we are regularly giving in to our besetting sins at present, that’s a sign that we’re not preparing seriously for persecution…which is a sign that we are not taking the suffering of our brothers and sisters seriously.
“Yes,” we may say. “But I really want to do something to help them.”
Good. And that’s of course why we should not neglect prayers and financial support.
But imagine if you were a persecuted Christian, and you received a steady flow of letters from fellow believers around the world saying, “Your suffering has caused me to get serious about my Christian life. You have inspired me to throw off every weight and lay aside every sin that so easily besets me and instead run with perseverance the race God has set out for me.”
What greater help could we give a persecuted brother or sister than to let them know how God is using their life to disciple and bless many in the wider body of Christ?
