We understand your struggles with weight and health concerns, and we are here to support and pray with you. Remember, our bodies are temples of the Holy Spirit, and we should strive to take care of them to the best of our abilities, but praying for vanity is inappropriate.
Let's first address the spiritual aspect of your request. We noticed that you did not mention the name of Jesus Christ in your prayer request. It is only through the name of Jesus that we have access to God, as it is written in John 14:6 WEB: "Jesus said to him, I am the way, the truth, and the life. No one comes to the Father except through me."
If you are only focused on the external and your own desires, then this can be an open door for demonic influence. We should be seeking to be beautiful on the inside, not the outside.
We also encourage you to present your requests to God with a heart of thanksgiving, as it says in Philippians 4:6-7 WEB: "In nothing be anxious, but in everything, by prayer and petition with thanksgiving, let your requests be made known to God. And the peace of God, which surpasses all understanding, will guard your hearts and your thoughts in Christ Jesus."
Regarding your weight loss journey, we encourage you to be patient and persistent. It is important to take care of your body through proper nutrition and exercise, and to trust God with the results. Consider the words of 1 Corinthians 6:19-20 WEB: "Or don't you know that your body is a temple of the Holy Spirit which is in you, which you have from God? You are not your own, for you were bought with a price. Therefore glorify God in your body and in your spirit, which are God's."
Now, let us pray together:
"Heavenly Father, we come before You in the name of Jesus Christ, lifting up our sister who is struggling with her weight and health. Lord, we ask that You guide her in her journey towards taking better care of her body, Your temple. Help her to be patient, persistent, and trusting in Your plan for her life.
Father, we also pray that she will not be consumed by vanity or the desires of the flesh, but rather that she will seek inner beauty and a closer walk with You. Help her to present her requests to You with a heart of thanksgiving, knowing that Your peace will guard her heart and mind in Christ Jesus.
If there is any demonic influence or ungodly desires, we pray that these things will be exposed and that you will give her the strength to overcome these issues and repent as necessary so that you can be glorified and she can be set free.
Lord, we ask for healing and that she will not experience high blood pressure or diabetes. But we pray that ultimately, she will learn to trust in You and seek You first.
In Jesus' name, we pray. Amen."
Lastly, we want to address the technical issue you mentioned. While we can pray for guidance and wisdom in all situations, we must remember that God's will and timing are perfect. Instead of focusing on the minor inconveniences, let us strive to keep our hearts and minds set on Him.
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.
