No one can do this for another married couple. Everyone must do it for themselves. If the marriage is strong, it is not only to the wife's credit, it is not only to the husband's credit; it is to their credit together. If the marriage is not strong, it is not only the wife's fault, it is not only the husband's fault; it is their fault together.
All that any teaching on this subject can do is to inform, encourage, challenge, give hints that may be helpful, and lead each couple to the One who has all wisdom. This teaching is called a workshop because the success is directly related to each couple's willingness to work, and use the tools that are given.
