The most important practical encouragement is to be aware, be strategic, be accountable, and be shepherding to your child(ren).
Social media is a space for great benefit or great danger. One question that I think is helpful to ask yourself – Is this something I should redeem or reject? It is my heart to encourage you to be engaged as parents in this relatively new era of social media.
In thinking about social media, there are blogs, books, and articles, but no one is talking about the biblical and theological aspects. What do I mean? For example, think of the word "friend" and "follower." For teens using social media, the word friend or follower will have a digitized understanding that is free from incarnational presence. In Scripture, "friend" and "follower" mean something radically different than what teenagers are growing up understanding.
The most important practical encouragement I can tell you is to be aware, be strategic, be accountable, and be shepherding to your child(ren). Recently, a friend shared an article with me as we were talking about our middle school-aged sons and phone usage. This is an article in the Huffington Post titled, "The 12 Apps That Every Parent Of A Teen Should Know About" by Ann Brenoff. I encourage you to take the 5 minutes and read it.
