Your prayer for your husband in this hour of heavy sorrow is heard, and it is a tender and Christlike desire to be made a comfort to him while he watches beside his grandmother in her frailty.
The Lord is the Father of mercies and the God of all comfort, who comforts us in all our tribulation. That comforting assurance is for them that fear Him, for the Angel of the Lord encamps around them that fear Him and delivers them. You and your husband are a people who need to be comforted, and the prophet was inspired to say, Comfort you, comfort you my people, says your God, speak you comfortably to Jerusalem and cry unto her that her warfare is accomplished, that her iniquity is pardoned. This is the comfort that abides, that even when the heart is heavy and tears flow, the soul may rest in the Lord.
It is right that you long to be used of God for your husband, for in a true marriage the husband and wife become one, and the Lord has joined you together that you might bear one another's burdens and reveal His own faithful love. As you are apart, he there on the island and you here in the states, remember that the Keeper of Israel never slumbers, He sees you both all the day long and all the night long, and He can make your prayers an overflow into his soul though distance divides you. Blessing God in this trial will itself be a comfort to you, for it takes the thoughts off our own sorrows and fixes them upon His unfailing goodness.
May the Lord flood your husband with support as he weeps, and hold him fast when his heart is overwhelmed. May He comfort you also as you wait and intercede, and teach you both to rest in the Lord, fixed upon that blissful center, and to say with ardent faith, I know, O Lord, that Your judgments are right and that You in faithfulness have afflicted me. Cast away sinful unbelief and look to Christ alone, for salvation is through Jesus Christ alone, and He is our only hope in life and in death.
We pray that the Lord will sustain his grandmother, and if it be His will to call her home, that He will receive her to Himself and give peace to those who love her. We pray that He will make you, though far away, a vessel of His encouragement to your husband, that your love, your prayers, your words spoken in the fear of the Lord, may uplift him emotionally, mentally and spiritually. May your marriage be strengthened through this sorrow, as you tell your griefs to your Lord as a wife tells her husband, and find Him to be a Husband to His people in faithfulness and tender care.
May the God who has comforted, who is comforting, and who will never leave off comforting you, keep you both in His perfect peace until you are reunited, and cause you to bless His name together.
