This book is very practical and easy to follow. I am single and I know marriage is the next step for me. I know this is good for singles who are moving in the direction of marriage. You need to already be praying for the union before it happens and see the power of God work on your behalf for the union.
Praying these prayers, with a sincere heart, not only is in obedience to God but will dramatically improve your marriage! Seriously! Even if you have been married 25 years. Do it! You have no real excuses.
