We understand that you're going through a challenging time with health issues affecting you and your loved ones. First, we want to remind you that God is always with you, and He cares about your needs. It's wonderful that you've included Jesus' name in your request, for it is by His name that we have access to God.
In times of trouble, remember what the WEB says:
Isaiah 41:10 "Do not fear, for I am with you. Do not be dismayed, for I am your God. I will strengthen you. Yes, I will help you. Yes, I will uphold you with the right hand of my righteousness."
Regarding your health concerns God's Word tells us:
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."
It's important to seek God's will in all situations, including health matters. Pray for healing, but also trust in God's wisdom if He has other plans. Remember that even in suffering, God can use it for good.
Romans 8:28 "We know that all things work together for good for those who love God, to those who are called according to his purpose."
Now, let's pray together:
Dear Heavenly Father,
We come before You in Jesus' name, lifting up our brother/sister who is facing health challenges. We pray for Your healing touch upon their body, specifically the polyps in the gallbladder and the growth on their son's tongue. We ask that You spare them from serious illness and that these issues would not be harmful and completely resolved.
Thank you for your help in this matter.
We also lift up their family member with the thyroid nodule. We pray that it would not be cancerous and that Your healing power would be at work in their body as well, and that the clan is well and truly healed.
Father, we ask for Your peace to fill their hearts and minds, casting out all fear and anxiety. Help them to trust in You and Your goodness, even in this difficult time.
We ask all of this in Jesus' name, who taught us to pray and who brings us to you as our High Priest for ever.
Amen.
Regarding the surgery, pray for wisdom and seek advice from medical professionals. It's important to consider their advice while also trusting in God's will. Don't let fear guide your decisions, but rather, seek God's peace and guidance.
Matthew 9:22 "But Jesus turned, and when he saw her, he said, Daughter, be of good cheer. Your faith has made you well. And the woman was made well from that hour."
Prayer Focus: God, Thank You for loving me. God, I ask You in Jesus’ name please bless me with everything that I stand in need of and everything You want me to have.
