Oh, I could write for days on this subject. It has been on my mind for quite awhile. Two links for you, one from the Chile Santiago mission president's wife about their pre-earthquake warning. Another from a fireside by Sister Bednar about the promptings of the Spirit.
It is our greatest responsibility to teach our children to recognize the Holy Ghost. My oldest is 9 now, and he still struggles with this. My husband pointed out to him that it may be harder for boys to feel the Holy Ghost, because they are not as in touch with their feelings. It was such an insight for me when he said that. Now I can look for opportunities to help him recognize all of his feelings, in hopes that it will help him recognize when he feels the Holy Ghost.
