Linda, I love your ideas. I give a workshop on writing devotionals.The importance of the legacy we leave to our generations to come is at times underestimated. Writing our experiences with the Lord is a great legacy to leave our loved ones.
Prayer as a ministry is a great idea too. So many blessings flow from it. I've seen it in my own ministry.
Donna, perhaps a seminar on cooking nutritious meals would interest older ladies, as their experience is vast on cooking, and helping younger women learn to cook nutritiously can be done as a ministry.
