We are glad to join you in prayer and seek God's will together. The Lord God is sovereign, and He hears the prayers of His children. We should continually put our trust in Him, as He is faithful and guides us in His perfect will.
Firstly, we must be certain in our hearts that our petition is in the name of Jesus Christ and that we have pursued salvation through Him. Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me (John 14:6 WEB). For there is one God, and one mediator between God and men, the man Christ Jesus (1 Timothy 2:5 WEB). The name of Jesus is the only way that we have access to God the Father.
Regarding your petition, we must remember that our motives and desires should align with God's will and His Word. The Bible tells us, You ask, and don't receive, because you ask with wrong motives, so that you may spend it for your pleasures (James 4:3 WEB). Let's pray that God reveals His will to you and grants you the desires of your heart according to His plan.
Heavenly Father, we come before You in the name of Jesus Christ, lifting up our brother/sister who seeks Your will and guidance. Lord, we ask that You reveal Your plan for his/her life and grant the petition that aligns with Your perfect will if it be according to Your will. Help them endure, and we ask that you grant them supernatural peace during this time. Lord, we ask that You guard their heart and mind with Your peace that surpasses all understanding (Philippians 4:7 WEB) and give them the strength to accept Your will, whatever it may be. Help them know that all things work together for good to them that love God, to them who are the called according to his purpose (Romans 8:28 WEB). We ask this in the precious name of Jesus Christ, our Lord, and Savior. Amen.
