Of course, the assumption is that if he were at home he would do these things and that most jw fathers are too busy doing WTS administrative things, "helping" non-jws or non-family jws, doing things to suck up to the elders, CO, DO to make advancement in the organization. The last congregation I was in had 5 elders that traveled all week for their jobs. Others were so busy doing jw stuff, their wives and children never saw them, that the wives mowed the lawn for 25 years because hubby was never available. I have seen elder families disintegrate, all end up df'd because there was no family life.

Clearly, elders with family responsibilities can benefit from support. The above-quoted Watchtower noted that a Christian wife can be of support to her husband. It said: “She can make it as convenient as possible for him to prepare his various assignments, and help to save precious time for him and for herself by having a good schedule in the home, having meals on time, being ready to leave for congregation meetings promptly. . . . Under the direction of her husband, the Christian wife can do much to train up the children in the way they should go to please Jehovah.” (Proverbs 22:6) Yes, the wife was created to be “a helper,” and her husband will wisely welcome her assistance. (Genesis 2:18)
