Being thankful should not be just a reaction to getting what you want, but an all-the-time gratitude, the kind where you notice the little things and where you constantly look for the good, even in unpleasant situations.
If your attitude toward your spouse is critical, unloving and generally disappointing, I would almost guarantee that you have not spent time telling God how thankful you are for him/her and that you haven’t told your spouse thank you to his/her face lately either.
Spend time in prayer thanking God for your spouse. If you are having a hard time coming up with something to be thankful about, start by being thankful that God created him/her. If nothing else, tell God you are thankful that He isn’t finished with your spouse.
Tell God you are thankful that you have someone to do life with, even if things aren’t going as well as you had expected. Even if your marriage is feeling really tough right now, even if it seems you could not be more opposite from your spouse if you had intentionally tried to marry your polar opposite, still thank God for him/her.
HUSBAND: Thank your wife for being a submissive wife and a confidant. Thank her for being a partner that you can rely on. For helping to keep peace at home, and for helping you raise the children. Appreciate her for praying for you and for all her support.
WIFE: Thank your husband for all the love he has showered on you and the children. Appreciate him for all the sacrifices he has made for the family in that he has preferred you before himself. Thank him for being a godly example for the family. Be grateful for the shelter and defence he has built around you and the children.
If married couples will spend their days appreciating each other and being thankful for each other, there will be less strife in the home and more joy and happiness.
