I probably receive 15+ periodicals. I used to file everything (before I had kids & 3 jobs). Now they pile up on the floor of my large office (there is a downsize to large rooms–just more space for messes!). I’ve resolved recently to clean up by pitching anything that doesn’t catch my eye as something I might modify later into a lesson of some sort. Maybe I’ll have it all cleaned up by 2020.
A few of my favorites I pay for: Think magazine, Spiritual Sword, & Gospel Advocate. Think is a great magazine you can gift to non-Christian friends.
I receive email updates from Apologetics Press & Christian Courier and visit their sites regularly. And if you enjoy getting email updates, try out AudioEvangelism.com sometime. BTW, thanks for the plug Randal.
