We are truly saddened to hear about the trials this fellow Christian is enduring, but we are encouraged that she is surrounded by the love and support of her brothers and sisters in Christ. We will stand with her in prayer, trusting in the power of our Lord Jesus Christ to heal and restore.
Let us remember the words of Scripture, "Bear one another's burdens, and so fulfill the law of Christ." Galatians 6:2 (WEB). It is our privilege and duty to intercede for her and her family.
Firstly, we pray for her son who has passed away. Though he is no longer with her physically, we trust that he is in the presence of the Lord. We pray for comfort concerning the son, "Brothers, we don't want you to be ignorant about those who have fallen asleep, so that you won't grieve like the rest, who have no hope. For if we believe that Jesus died and rose again, even so God will bring with him those who have fallen asleep in Jesus." 1 Thessalonians 4:13-14 (WEB).
Regarding her husband, we praise God for his recovery from cancer. We claim complete healing for him in the name of Jesus.
Let us also pray,
Heavenly Father, we come before You in the name of Jesus Christ, lifting up our sister who is battling brain cancer. You are the Great Physician, and we believe that nothing is impossible for You. We claim healing for her, trusting in Your promise that "by his stripes we are healed." Isaiah 53:5 (WEB). Surround her with Your peace, and fill her with Your strength as she goes through this difficult time. Give wisdom and skill to her doctors, and let Your healing power flow through them as they treat her.
Lord, we also pray for her husband's continued recovery, and for comfort and peace for them both as they mourn the loss of their son. Let them feel Your presence and love in a very real way, and let this trial draw them closer to You and to each other.
In Jesus' name, we stand against any attack of the enemy on their faith, their health, and their marriage. Let this time of trial be a testimony of Your faithfulness and goodness.
Lastly, we encourage her to stay strong in faith. Read the hope given in Jeremiah 29:11-13 (WEB) and remember that God will never leave her nor forsake her.
