We are truly concerned for your mother-in-law's situation and we will pray for her together. In moments like these, it's crucial to remember that God cares for our every need and hears our prayers. It's also important to act wisely in urgent situations.
Firstly, we want to address the urgency of the situation. It's commendable that you're trying to call someone to help, but if your mother-in-law is indeed very badly off and cannot get up, it may be wisest to call emergency services without delay. It's better to be safe and ensure she gets the help she needs. Safety and health are paramount for a child of God. It's better that you call for help publicly rather than trying to stay socially distant. The story of the good Samaritan is relevant here as he did not stay aloof but helped. Please consider these verses from the WEB:
Love one another: just as I have loved you, you also love one another. By this everyone will know that you are my disciples, if you have that may have love for one another.
Proverbs 3:5-6 Trust in Yahweh with all your heart, and don't lean on your own understanding. In all your ways acknowledge him, and he will make your paths straight.
If anyone says, I love God, and hates his brother, he is a liar; for he who doesn't love his brother whom he has seen, how can he love God whom he has not seen?
Additionally, you did mention Jesus in your prayer. This is good because it's important to remember that it is only by the name of Jesus that we have access to God. As it says in the WEB:
There is salvation in none other, for neither is there any other name under heaven, that is given among men, by which we must be saved!
Now, let's pray together for your mother-in-law:
Heavenly Father, we come before You in the name of Jesus, lifting up our dear mother-in-law who is in urgent need of help. Lord, we pray for Your divine intervention, that You would prompt a neighbor or someone nearby to come to her aid immediately. Guide those who are trying to help her, and Lord, if it is necessary, prompt those who need to call emergency services to act quickly.
We pray for Your healing touch upon her, that You would restore her strength and give her the ability to get up. Comfort her with Your presence, and remove all fear and anxiety. Lord, we also pray for those around her, that You would give them wisdom and discernment to make the right decisions for her well-being.
We ask this in the powerful name of Jesus, who teaches us to love one another just as He has loved us. We pray for a miraculous recovery in Jesus name. We also ask that you give wisdom to the doctors and medical personal and a healing touch. We thank You, Lord, for Your unfailing love and faithfulness. In Jesus' name, we pray. Amen.
Please keep us updated on her situation, and know that we are here to support you in prayer and counseling. If you can get her any medical attention, please do so.
