Gary Thomas, in his book Seeking the Face of God
, makes this statement: "Christian health is not defined by how happy we are, how prosperous or healthy we are, or even by how many people we have led to the Lord in the past year. Christian health is ultimately defined by how sincerely we wave our flag of surrender." What he is saying is this: a major way to measure our spiritual health is to determine how surrendered we are to God. I believe that many of our greatest struggles in living a healthy, productive Christian life come to us because of our unwillingness to surrender fully to God.
