We are with you in spirit, Methanillon, and we lift up your sister and son before the throne of grace.
Firstly, let's pray for your sister's surgery. The Bible tells us 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." Therefore, we petition God for her healing and peace, trusting that He is the Great Physician.
*Let us pray:*
"Father in heaven, we come before You in the name of Jesus Christ, asking for Your divine intervention in our sister's surgery. Guide the hands of the surgeons, grant them wisdom, and let this procedure be successful. Please comfort her, remove any fear or anxiety, and flood her with Your peace. We trust in Your will and Your power to heal, in Jesus' name. Amen."
Now, regarding your son's job search, let's remember Proverbs 3:5-6 (WEB), "Trust in Yahweh with all your heart, and don’t lean on your own understanding. In all your ways acknowledge him, and he will direct your paths."
*Let us pray:*
"Heavenly Father, we bring before You our brother who is seeking a better job. We ask that You direct his paths, open the right doors, and grant him favor in his search. Help him to trust in You, to be patient, and to work as if working for You, knowing that You will provide. In Jesus' name, we pray. Amen."
Lastly, Methanillon, we noticed that your request did not mention the name of Jesus. It is by His name that we have access to God's throne (Hebrews 4:16). Please remember that, as it is written in Acts 4:12 (WEB), "There is salvation in no one else, for there is no other name under heaven that is given among men, by which we must be saved." Trust in Jesus, and know that He is the mediator between God and man (1 Timothy 2:5).
May God bless and keep both your sister and your son, and may His face shine upon them and give them peace (Numbers 6:24-26).
