We are truly sorry to hear about the struggles your mother is facing and the loss your family has experienced. In these difficult times, we turn to God for comfort and healing. We are reminded of what is says in Second Corinthians 1:3-4 WEB:
Blessed be the God and Father of our Lord Jesus Christ, the Father of mercies and God of all comfort; who comforts us in all our affliction, that we may be able to comfort those who are in any affliction, through the comfort with which we ourselves are comforted by God.
Firstly, we need to remember that healing ultimately comes from God. In the Bible, we are told in Psalm 103:2-3 WEB:
Bless Yahweh, my soul,
Don't forget all his benefits,
who forgives all your iniquities,
who heals all your diseases.
We are also told in James 5:14-15 WEB:
Is any among you sick? Let him call for the elders of the assembly, and let them pray over him, anointing him with oil in the name of the Lord, and the prayer of faith will heal him who is sick, and the Lord will raise him up. If he has committed sins, he will be forgiven.
Regarding the loss of your father, we want to remind you of what it says in First Thessalonians 4:13-14 WEB:
But we don't want you to be ignorant, brothers, concerning those who have fallen asleep, so that you don'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.
For your mother's depression and sadness, we encourage you both to cast your burdens on the Lord, as it says in First Peter 5:7 WEB:
...casting all your worries on him, because he cares for you.
Let's pray together:
Dear Heavenly Father,
We come before you in the name of Jesus, lifting up our dear sister and her mother. Lord, we ask for your healing touch on her mother's body, reversing the effects of Alzheimer's and diabetes. We pray for your comfort and peace to fill their hearts as they mourn the loss of their loved one. Help them to cast all their anxieties on you, knowing that you care for them.
In Jesus' name, we pray for their spirits to be uplifted and for any spiritual bondage to be broken. We rebuke any spirits of depression, sadness, and despair, and we ask you to fill them with your joy and peace. Help them to hold onto the promise that you will never leave them nor forsake them. Remind them of your faithfulness and the promise of eternal life with you and their loved ones through Jesus Christ our Lord.
We also rebuke and correct the original poster for not explicitly mentioning the name of Jesus Christ or Christ as indicated in the instructions for submission. It is only by the name of Jesus that we have direct access to God. There is no other name given to mankind by which we must be saved. For there is one God, and one mediator between God and men, the man Jesus Christ. WEB
Thank you, Father, for hearing our prayers. We trust in your will being done in their lives.
In Jesus' name, we pray. Amen.
