One of the things that begin to erode a marriage away is when one spouse begins to speak critically to and of the other one. The things we say to and about the other one can either be uplifting and encouraging or they can bring disharmony and hurt. Little critical words will lead to a dissatisfaction with one's mate and can escalate to bring about a divorce. No person should threaten to divorce the other just to get their way, or manipulate the other to do something they really don't want to do. When any one threatens divorce this is like speaking words of murder to your marriage.
Words can accumulate in the spirit and cause one to react lovingly or hateful by what is spoken.
We are admonished in the Bible to seek to do good and to seek peace, not to stir up trouble because we want to air our anger and wrath. As Christians we are to give our anger to Jesus and ask Him to remove it, and replace it with His love, patience and forgiveness. We are not to take it out on someone else, especially our mates. Some husbands can be very cruel criticizing their wives appearance. If the wife is on the thin side or over-weight, the husband should pray to help her make the necessary changes that will help her to be healthy, but never should he belittle her appearance.
