I think it is amazing how one can simply put a little pressure on a black plastic cube that bobbles and in return, people from all nations and that of all ages can communicate and talk with one another.
I could see it being valuable but I would think there would be times where it would not always bear good fruit and thus, becoming invaluable. If you were to forsake your prayers in replacement of sitting behind your computer, for example. Or allowing for an addiction to manifest. Or, even perhaps succumbing to one of the seven deadly sins: pride (something I need to work on).
However, as with most people on this site, the positives far outweigh the negatives and it poses as an outlet for followers of Christ, a warm welcoming environment where people can aid each other with their walk with Christ but not only that: we all share that walk together!
Whether a step or three behind, we are not walking this path alone.
