Some churches have memorial services to remember those who have gone on before us at this time of year to help ease the pain of loss so that Christmas isn't a sad memory for them, but rather a celebration still of Jesus and of the life of the person they lost.
How can people have peace this time of year when dealing with loss? The loss of a loved one or a job or something else? We turn to God. Only we as believers have hope beyond the pain, it is a hope that only Jesus can give through the power of the Holy Spirit. As John 14:27 says, 27 Peace I leave with you; my peace I give you. I do not give to you as the world gives. Do not let your hearts be troubled and do not be afraid.
We are given a peace in times of trials and loss that the world simply cannot understand apart from Christ. So to those who are dealing with loss this time of year, of loved ones or employment or something else, may the Lord be with you at this time. I don't say that as a pat answer, but to encourage you that there is hope and peace that you can claim in Jesus today.
