While I feel that I should apologize for saying this, I won’t. Its just the reality of the matter. There is no app for letting people know that you live in Christ and that the Holy Spirit lives in you. No widget. No development tool. No social network. No spam. Nothing. You have to livewith others for them to eat from the Tree you say you belong to. Trying to put mobile, web, or otherwise in the way is thorny, immature, and self-defeating.
So before you download that next app that you want to show to familiy and friends, just remember that Jesus bears witness to the person reflecting Him, not the mobile device reflecting a piece of what He created.
