Predictions are a dime a dozen, and predictions about the church in the western world can be awfully generalised. Nevertheless, I found some predictions and warnings by Carey Nieuwhof were worth considering.
The predictions clearly relate to the North American church (Carey is Canadian), so a few probably won’t apply to countries like Australia and Great Britain where the church has long been a minority culture, but I’m sure you’ll find a few that are relevant to you. Carey has presented some of his observations as negatives (i.e. things NOT to believe), but I have re-worded them as positive truths to make them all consistent.
