I’m so sorry to hear about your recent loss. I’ll be praying that the Lord will make His invisible presence very real to you, and that He Himself will intervene in amazing ways to fill the empty places in your heart. We know that God uses significant loss to draw us into an ever deeper dependence upon His all-sufficient grace. But this knowledge does little to remove the heartache you’re feeling at this time. The death of your husband may be the most painful event you’ll ever experience in life -- how could it be otherwise, when the two of you were “one flesh”? But the Lord knows you intimately; and in those moments when you feel unable to go on, He’ll be there to carry you through.
Also, if you haven’t already done so, I encourage you to speak with the pastor at your church regarding what you’re going through. They’d certainly be in an excellent position to offer support. Rest in the assurance that Jesus Himself has promised never to forsake you. He can make your burden lighter -- and I trust that He will.
