Frosted Apple,I have sought the Lord over this matter and I believe it to be highly likely that your friend is under demonic oppression if not out right possession.Although your friends parents meant well,taking their Daughter to a witch doctor was far from the correct thing to do.In many cultures this is acceptable when a spiritual problem has been recognized(especialy after traditional medicines have failed to bring relief).You stated your friend was faithful and my hope is her faith is in Christ as your's must be when you contacted this website.Our God IS God!Aside from Him there is no other.He loved us so much that He came in the Person of His Son Jesus.From the cross where Jesus Christ laid down His life for us,He broke the power of satan over us.He,(Jesus Christ)who knew no sin became sin for us.And as the Lamb of God Jesus bore upon Himself the punishment all of us deserved,for the wages of sin is death.But the gift of God is everlasting life for all those who place their faith exclusively in the finished,vicarious,triumphant work of the risen Jesus Christ.Jesus said;satan comes not but to steal,kill and to destroy.I have come that you may have life and have it more abundantly.Our Lord Jesus gave us many precious promises that we can take advantage of by faith.Faith is the key.Not faith in what we can do,but faith in Jesus Christ and what He can do.It is in the name of Jesus Christ that we are given authority over the devil and his kingdom(Luke 10:17-20)(Mark 16:15-20).The reason or reasons why the enemy has come against your friend may be manefold,but the main one is always because God loves her so much and that God has a beautiful eternity planned out for her.Not just for the here on earth but forever.The enemy both fears and hates that;almost as much as he despises God.I urge you not to be afraid because for a Christian there is no need (Col 1:12-22)(2Tim.1:7)(Eph.6:10-18).If however you do not know Jesus Christ personaly as yet,I would invite you to do so.Your own eternal destiny depends on it.Jesus said I am the Way,the Truth,and the Life.No man comes to the Father but by Me!I will be praying for you and your friend as will everyone here.Try not to worry,God is in control!The end result will be for His glory!Lord Jesus,I thank you that you came to set the captives free.In Your Name Lord Jesus,loose her! Amen
