We understand that you are going through a very difficult time, and we are here to pray with you and provide biblical guidance. We commend you for acknowledging Jesus in your prayer. First of all, let us affirm the truth that God cares about you deeply and wants to help you in your struggles. Remember the words of Jesus in Matthew 11:28-30 (WEB):
Come to me, all you who labor and are heavily burdened, and I will give you rest. Take my yoke upon you, and learn from me, for I am gentle and lowly in heart; and you will find rest for your souls. For my yoke is easy, and my burden is light.
Learning a new language can be a positive step, but it is crucial to address the spiritual and emotional turmoil you are experiencing. The issues you mentioned, such as schizophrenia, demonic behavior, and the effects of pornography, are serious and require spiritual intervention and possibly professional help.
Firstly, let's address the issue of pornography, as it is a sin that can have severe consequences on your mental and spiritual well-being. 1 Corinthians 6:18-20 (WEB) says:
Flee sexual immorality! Every sin that a man does is outside the body, but he who commits sexual immorality sins against his own body. Or don't you know that your body is a temple of the Holy Spirit who is in you, whom 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.
Repent of this sin and seek God's forgiveness. He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness (1 John 1:9 WEB).
Regarding the torments and voices you are experiencing, it is essential to seek deliverance and healing through prayer and possibly Christian counseling. Jesus has given us the authority to cast out demons and heal the sick (Mark 16:17 WEB).
Now, let us pray for you:
Dear Heavenly Father,
We come before You in the name of Jesus Christ, lifting up our fellow believer who is going through a time of great turmoil. Lord, we ask for Your healing and deliverance from the schizophrenia, demonic behavior, and the effects of pornography that have been plaguing their mind and spirit. We rebuke any evil spirits that may be influencing these thoughts and behaviors, and we command them to leave in the mighty name of Jesus Christ.
Father, we ask for Your guidance and wisdom as they seek to learn a new language and find a new life in Japan. Please provide them with godly friends and a supportive community that will encourage them in their walk with You. Give them confidence in their future and replace any thoughts of death with Your hope and purpose.
Thank You, Lord, for Your peace, providence, and progress in their life. We ask all these things in the powerful name of Jesus Christ, our Lord and Savior. Amen.
Lastly, we encourage you to continue seeking God's will for your life and to trust in Him. He has a plan and a purpose for you, and He will guide you through this difficult time. Stand firm in your faith, and do not be swayed by the trials you are facing. Remember that God is with you and that He will never leave you nor forsake you (Hebrews 13:5 WEB).
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.
