We are truly sorry to hear about your mother's health situation and we are here to pray and offer support. First of all, we thank God that you are acknowledging His power by invoking the name of Jesus. It reminds us in John 14:13-14 WEB, "Whatever you will ask in my name, that will I do, that the Father may be glorified in the Son. If you will ask anything in my name, I will do it".
In times of sickness and injury, we remember the Lord's promises to us, such as in Psalm 103:2-3 WEB, "Bless Yahweh, my soul, and don't forget all his benefits; who forgives all your sins; who heals all your diseases". We pray for your mother's healing, that God will mend her broken leg, and ease her discomfort. We ask God for complete healing, in body, soul, and spirit. We also pray for the doctors and nurses treating her, that God will guide their hands and give them wisdom to provide the best care for your mother. We also pray that any distressing symptoms, such as the loose motion, will subside quickly.
While we pray for healing, we also acknowledge God's sovereignty. Even in trials, we know that God is faithful. As it says in 1 Corinthians 10:13 WEB, "No temptation has taken you except what is common to man. God is faithful, who will not allow you to be tempted above what you are able, but will with the temptation also make the way of escape, that you may be able to endure it". Your mother's faith will likely be tested in this time. We pray that she will feel God's presence and peace, and that her faith will only grow stronger.
Regarding the financial concerns, we remember Jesus' words in Matthew 6:25-34 WEB. He tells us not to worry about what we will eat or drink or wear, but to seek first God's kingdom and his righteousness. We pray that God will provide for your mother's medical expenses, whether that be through insurance, generous friends and family, or other means. We ask that God will give you and your mother peace about the financial situation, and that you will trust in His provision. We also pray for wisdom in making decisions about insurance or other financial matters. Finally, we pray that God will give you and your family strength and endurance during this time. Wait on the Lord, you will gain new strength; you will mount up with wings as eagles; you will run, and not be weary; and you will walk, and not faint. Let us all pray.
Father in heaven, we come before You in Jesus' name, asking for Your healing touch on this dear mother. We pray for her broken leg, that it will heal quickly and completely. We ask for Your comfort and strength for her and her family during this time. We pray for wisdom and provision for the medical expenses. We trust in Your promises, and we thank You for Your faithfulness. In Jesus' name, we pray. Amen.
