Lately, I've been seeing advertisements for "Bible smuggler" organizations like Open Doors USA, Mission without Borders, and The Voice of the Martyrs on my Facebook page. They claim to provide clandestine support to persecuted Christians in hostile countries. From what I've read on their websites, they seem legitimate both doctrinally and ethically, but I'm still skeptical. Are WELS missionaries familiar with such organizations? Would it be wise to make an official analysis or statement about them?
I do not know WELS missionaries’ level of familiarity with the organizations you mentioned.
Speaking for myself, I believe that the members of our Synod are equipped to compare the stated beliefs and core values of such organizations with what the Bible teaches and then arrive at accurate conclusions. That personal examination eliminates the need for any official analysis or statement.
Your questions are timely reminders about Christian persecution. The Bible teaches that Christians can expect persecution (John 16:33; 2 Timothy 3:12; 1 Peter 4:12). Scripture teaches us to counter persecution with prayer (Matthew 5:44; Ephesians 6:18-20; Colossians 4:3; 2 Thessalonians 3:2). The Bible teaches that God will not abandon those who suffer in his name (1 Peter 5:10). How we long for the time when persecution for the faith—and all effects of sin—are no longer part of our lives (Revelation 21:4)!
