We understand that you're going through a tremendous amount of spiritual, emotional, and physical distress. Firstly, we want to assure you that your faith in Jesus is the most powerful weapon you have against the voices and lies of the enemy. The Bible tells us, For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places. Ephesians 6:12.
Let's address the issues one by one. You mentioned that you hear voices telling you that you have no hope of ever getting a spouse and that your destiny is being given to someone else. Know that this is not from God. God's plan for you is to prosper you and not to harm you, plans to give you hope and a future. Jeremiah 29:11. The enemy is a liar and the father of lies. John 8:44. Rebuke these voices in the name of Jesus, for there is no other name under heaven given among men by which we must be saved. Acts 4:12.
You mentioned that you want to put your faith in Jesus but feel that your peace is gone. Remember, Jesus has said, Peace I leave with you, my peace I give unto you: not as the world giveth, give I unto you. Let not your heart be troubled, neither let it be afraid. John 14:27. Your peace is found in Him and Him alone. Fix your eyes on Jesus.
Regarding your fast, it is important to honor your parents. Ephesians 6:2 says, Honor your father and mother, which is the first commandment with a promise. However, if you feel strongly led to fast, perhaps you can share your convictions with your mother at an appropriate time and in a respectful manner. God will always honor a heart that is fully committed to Him.
About your physical ailments, we believe that Jesus took our infirmities and bore our sicknesses. Matthew 8:17. Pray for healing in Jesus' name. Trust His power to heal you from the top of your head to the soles of your feet.
Lastly, addressing sexual frustration, it is important to remember that sexual immorality is a sin against your own body, which is the temple of the Holy Spirit. 1 Corinthians 6:18-19. Flee from sexual immorality. Every sin that a man does is outside the body, but he who commits sexual immorality sins against his own body. Or do you not know that your body is the temple of the Holy Spirit who is in you, whom you have from God, and you are not your own?
Let us pray together:
Dear Heavenly Father,
We come before You in the mighty name of Jesus, lifting up our brother/sister in their time of need. Lord, we rebuke the voices of the enemy that are speaking lies and causing distress. We declare that You have a hope and a future for them, including a godly spouse if that is Your will. Restore their peace, Lord, as they fix their eyes on Jesus.
Lord, we ask for wisdom and guidance regarding the fast and the relationship with their mother. Heal their physical ailments, Lord, from the top of their head to the soles of their feet. We also pray for deliverance from sexual frustration and for a heart that desires purity and holiness.
Lord, we thank You for Your faithfulness and Your love. We know Your will is the best for our brother/sister. Teach them all things and give them the mind of Christ. Thank You Jesus for saving us and giving us access to God. Be with them and lead them in the path everlasting.
In Jesus' name, we pray. Amen.
