1 Timothy 3

In this chapter, Paul lays out the qualifications of a priesthood holder and especially the office of bishop. His qualifications go along with what is said in D&C 121. What he says that isn't in the D&C is that wife of an office holder should be honorable and righteous. It is not unusual in the church that when a man is considered for a demanding or important calling such as bishop, it is the wife that is considered first. If she isn't dedicated and supportive, it would be very difficult for the man. A wife must be willing to sacrifice a great deal for her husband to hold such callings since he will be given extra burdens of responsibility and required to be gone many hours during the week. There are great blessings that come from this, but isn't easy for the wife. The Lord knew what he was doing, because if the roles were reversed, I'm not sure how well some men would do.
