I think the best way is for husband and wife to agree together that THEY will put God first. It is not a matter of putting God first before your wife, because in His eyes you are "one flesh". In this way, one will not dominate the other and use God as a nail to hang one's hat on.
A husband may tell his wife, "God told me that we have to shift to [wherever] and because I put God first, I will have to go whether you go or not." But if God has not told his wife as well, he might just be using God to do what he wants. But if during prayer and discussion, both husband and wife get the same message about moving house, and perhaps it is going somewhere with a colder climate and leaving their comfortable church and friends, then because God has told them both that He wants them to move, this is where they are putting God first over and above what they might have wanted to do - stay where their comfortable church is and where their friends are.
I once got an invitation to go and speak at a conference in Nigeria (a very long way from New Zealand). My wife was not happy about that prospect. She said that would worry herself to death all the time I would have been away. I knew that God did not want me to go to Nigeria, even though speaking at that conference would have been a great blessing to those people. But in reality, if I did go, God would not go with me because I would have caused my wife needless worry. Therefore, for me, putting God first was to stay home and not go to Nigeria.
