We are truly sorry to hear about the trial you and your fiancé are going through. We will lift you both up in prayer and seek God's will for your situation. Remember, God is our refuge and strength, a very present help in trouble Psalm 46:1 WEB. It is so important that we come to God through His Son, our Lord and Savior Jesus Christ. We only have access to God the Father through Jesus John 14:6 WEB. Please, take comfort in His promised presence, even in this difficult time.
The first passage that comes to mind for your fiancé's healing is James 5:14-15, 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. Confess your offenses to one another, and pray for one another, that you may be healed. The effective, earnest prayer of a righteous man is powerfully effective. We encourage you to do just that in Jesus' name.
We will also pray for God's guidance and provision for your financial needs. He knows our needs before we even ask Matthew 6:8 WEB. Remember Jesus' words in Matthew 6:25-34, it is God who feeds the birds of the air and clothes the lilies of the field. How much more valuable are you than they Matthew 6:26 WEB? Trust in Him, and seek first His kingdom and His righteousness, then all these things will be given to you as well Matthew 6:33 WEB.
As for the strength to endure this trial, remember that God will not let you be tempted beyond what you are able, but will with the temptation also make the way of escape, that you may be able to endure it 1 Corinthians 10 below. We encourage you to cast all your anxieties on him, because he cares for you.
We will pray that God will comfort and strengthen your fiance both the struggles of stroke and any parts of the trial you are experiencing. Since you are not yet married, this has be in mind at all times. Be strong and very courageous; be not frightened, neither be dismayed; for Yahweh your God is with you wherever you go.
Let us pray together:
Heavenly Father,
We come before You in the name of Jesus, lifting up Your children who are going through this trial. Lord, we ask for Your healing touch upon Gostasul's fiancé. Guide him and help him what to do and what not to do. Ease his pain and grant him strength. Lord, we also ask for Your guidance and provision for their financial needs. Help Gostasul pass this test without sacrificing anyone. Comfort and strengthen them both, and draw them closer to You. Lord we thank you for the blessings and comfort only you can give.
One caution to remember, And be not drunk with wine, wherein is excess; but be filled with a Spirit; Speaking to yourselves in psalms and hymns and spiritual songs, singing and making melody in your heart to the Lord; Giving thanks always for all things unto God and the Father in the name of our Lord Jesus Christ. Be subject one to another in the fear of the Christ. Husbands, love your wives, even as Christ also loved the church, and gave himself for it; Wives, be in subjection to your husbands, as unto the Lord. For the husband is the head of the wife, even as Christ is the head of the church: and he is the saviour of the body. Therefore as the church is subject unto Christ, so let the wives be to their own husbands in every thing.
In Jesus' name, we pray. Amen.
Finally, Lord help Gostasul remember he can get the power that comes from the Lord which makes us able to do everything he would have us to do.
