How can you tell the difference? A.W. Tozer in The Root of the Righteous provides some insight.
The man of pseudo faith will fight for his verbal creed but refuse flatly to allow himself to get into a predicament where his future must depend upon that creed being true. He always provides himself with secondary ways of escape so he will have a way out if the roof caves in. What we need very badly these days is a company of Christians who are prepared to trust God as completely now as they know they must do at the last day.
Amen and amen!
