God ordained marriage between a man and a woman for companionship, procreatioin, and so man would have a "helper suitable." However, God says much more in the Bible about husbands loving their wives than He says about wives submitting to their husbands. He created marriage to be a picture of the relationship between Christ and the Church. Christ was willing to sacrifice His life for the Church, and God expects no less from husbands today.
The overall purpose of "The Exemplary Husband" is to assist husbands toward purposeful and lasting Christlikeness for the glory of God. It was written to be the companion book for "The Excellent Wife" by Martha Peace. Foreword by John MacArthur.
