3a. "That they (older women) teach the younger women to be sober.

Sober

From the Greek word: (sophronizo)

1. Restore one to his senses
2. To moderate, control, curb, disciple
3. To hold one to his duty
4. To admonish, to exhort earnestly

Older women are to restore younger women to their senses, disciple them, hold them to their duties, and admonish them. So, being sober is to be sensible, controlled, moderate, do your duty.

It doesn't mean you can't laugh.

“Moderate” means "not in extreme." Kind of the same thing as sensible. Don't bounce off the walls. Stay steady and controlled. Do the job that God has called you to; do your duty.

What job has God called you to? If you have a husband, He has called you to be a help-meet to that man, (If he is a truck driver, you are called to be a truck driver’s wife. If he is a policeman, you are a policeman’s wife, etc.)

If you have children, He has called you to be a mother. These are your two primary, undeniable callings. All other callings must be secondary.

Now, God often gives us additional callings- such as my writing or leading worship in church- after we have proven ourselves faithful in the first two. But we must train ourselves (with the help of older women) to be steady and controlled- sober- in these two callings first.
