We have much Experience to Give?
Old folks should not be seen as being in the corner of fellowship, but in the front with the young children and those coming to faith to help and encourage them or keep them in line when they get over excited more the little ones I think!
Other wise we still have a long life of experience that we can warn those even a little younger than us what to do and what to avoid?
The Holy Bible tells us much about the older wise men in the gate and that is where younger men sought out that help and wisdom, so we should also be doing the same, woman to as much as men!
