Good ideas for funeral sermons include the religious beliefs of the deceased and his good traits while alive. Deeds he has done for others and community services should be mentioned. It's a good idea to discuss grieving, but in the context of moving on.
Accomplishments of the individual can be added to a funeral sermon, including excelling in his career or the degrees he earned in school. If the person had children, mention his family and parenting skills. Family members can request that the officiant share a special memory about the deceased. Eulogies should have an upbeat tone. Memories of happy times told with a bit of humor are highly encouraged.
