Usually when we consider the topic of contentment, we think of money and materialism. However, the concept extends to many other areas of life, including marriage. While most Bible references on contentment deal with the topic of wealth and possessions (i.e. Mat. 6:24-33, Phil. 4:11-13, 1 Tim. 6:5-11, Heb. 13:5-6), the same principles certainly apply to our attitude about life circumstances in general. Marriage is among the most important areas in which we must reflect this principle.
To be content simply means to be mentally and emotionally satisfied with the way things are. Someone who is content is willing to accept the current circumstances with peace of mind. People who are discontent in their marriage usually make themselves and their spouses miserable. Such people are never satisfied with what they have and are always wanting, expecting or even demanding more. Instead of recognizing the positive aspects of their spouse and marriage they focus on the negatives. Instead of expressing appreciation and encouragement they express criticism and resentment.
One does not need a perfect marriage (which does not exist) in order to be content. But a positive attitude and outlook is required. Begin by counting your blessings and not taking them for granted. While some problems must be addressed in a marriage they are best approached from a position of general contentment rather than that of perpetual displeasure or misery. People respond best to positive reinforcement and encouragement - your spouse is no different.
In life and in marriage, contentment is a virtue that is far too rare!
